The slope of a line is determined by its steepness.
The formula for calculating slope is expressed as;
[tex]\frac{\triangle y}{\triangle x} = \frac{y_2-y_1}{x_2-x_1}[/tex]
For the first graph, we can assume the coordinates (-1, 0) and (0, -2), the [tex]\frac{\triangle y}{\triangle x} = \frac{-2-0_1}{0-(-1)}\\\frac{\triangle y}{\triangle x} = \frac{-2}{1}\\\frac{\triangle y}{\triangle x} = -2\\\\[/tex]
Since the slope is -2 which is a negative value, hence the slope of LlNE 1 is negative
For the vertical line, since the line is parallel to the y axis and the change in the x-value is zero, hence the slope of LINE 2 will be UNDEFINED
For the THIRD graph, we can assume the coordinates (2, 0) and (0, -2), the [tex]\frac{\triangle y}{\triangle x} = \frac{-2-0}{0-2}\\\frac{\triangle y}{\triangle x} = \frac{-2}{-2}\\\frac{\triangle y}{\triangle x} = 1\\\\[/tex]
Since the slope is 1 which is a negative value, hence the slope of LlNE 3 is positive
For the horizontal line (fourth graph), since the line is parallel to the x-axis and the change in the y-value is zero, hence the slope of LINE 4 will be ZERO

It is known that Ray AP bisects angle CAT. If m<CAT = 5x+17 and m<PAT = 3x-4, then determine the value of x.
Answer:
x = 25
Step-by-step explanation:
It is given that, ray Ray AP bisects angle CAT. It means,
[tex]\angle CAT=\angle CAP+\angle PAT[/tex]
Also, [tex]\angle CAP = \angle PAT[/tex]
It gives, [tex]\angle CAT=2\angle PAT[/tex]
ATQ,
[tex]\angle CAT = 5x+17 \ \text{and}\ \text{PAT}=3x-4[/tex]
So,
[tex]5x+17=2(3x-4)\\\\5x+17=6x-8[/tex]
Taking like terms together,
[tex]5x-6x=-8-17\\\\-x=-25\\\\x=25[/tex]
So, the value of x is 25.

The ratio of the change in the y and x values, in the table gives the slope
graph of the linear function.
Correct response:
The slope of the linear function is -6
What is slope?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as, dx/dy.
here, we have,
Method used for finding the slope
From the given table, we have;
The first difference of the y-values = 2 - 8 = -6 = Constant
The rate of change of the x-values = 1 = Constant
Therefore;
The function is a linear function;
The slope, m, is given by the formula;
m = y2 - y1/x2-x1
Taking a pair of points as follows;
(0, -4) = (x₁, y₁)
(2, -16) = (x₂, y₂)
We have;
m = -6
The slope of the linear function, m = -6

find the coordinate of the midpoint of the segment with the given endpoints -7 and 8
Answer:
The coordinate of the midpoint is 1/2
Step-by-step explanation:
Midpoint
The midpoint of a segment defined in a one-dimension system is
[tex]\displaystyle \bar x=\frac{x_1+x_2}{2}[/tex]
Where x1 and x2 are the coordinates of the points.
The given segment has endpoints x1=-7 and x2=8, thus:
[tex]\displaystyle \bar x=\frac{-7+8}{2}[/tex]
[tex]\displaystyle \bar x=\frac{1}{2}[/tex]
The coordinate of the midpoint is 1/2
Suppose it takes John 18 minutes to run 3 miles. How long would it take him to run 7 kilometers? round to the nearest minute
Answer: 26 Minutes
Step-by-step explanation:
3 mi * 1.609 km/1 mi = 4.82 km
4.82 km/ 18 minutes = 7 km/ x minutes
4.82x=18*7
x=126/4.82
x=26.14 ~ 26 Minutes
One mile contains 1 mile = 1.690KM.
According to the if we convert 7km into miles 4.3496 miles. Thus the correct answer for the question is 26 minutes
Explanation:
That its taken the when john runs 18 minutes for 3 miles that is km4.82 than if we consider 1.34 miles is required to be covered more when subtract the value 4.3496-3.0000-1.34miles it should be 13is half of it multiply by 2 minutes more is required to cover the left distance is carried by Dividing 18by 1.34 and multiplying by 2
Thus we conclude that above answer to the Question is correct

The perimeter of a rectangle is 100 ft , if the wife is 20 ft what is the value of the length?
Answer:
30
Step-by-step explanation:
since the width is 20, there are 2 sides, so multiply by 2 and it's 40. Subtract 40 from 100 and you get 60. 60 is both lengths combined, so divide by 2 and you have 30 as your length. :)

Find the solution to the following system using substitution or elimination: y = 3x + 2 y = -2x - 8 O A. (-5,-) OB. (-2,-4) O C. (1,-6) O D. (-:-)
Answer:
B. (-2,-4)
Explanation
Given equations:
y = 3x + 2
y = -2x - 8
Solving both equations will yield the values of x and y;
Solution:
y = 3x + 2 ----- (i)
y = -2x - 8 ------ (ii)
Using substitution method, input equation i, into ii
3x + 2 = -2x - 8
Collect like terms and solve;
3x + 2x = -8 -2
5x = -10
x = -2
Then put x = -2 into i, to find y
y = (-2 x 3) + 2
y = -6 + 2 = -4
So, the solution of the equation is B. (-2,-4)

Zoe bought 1.5 pounds of apples for $3.50 per pound. She wanted to find the total cost using partial products.
Answer:
She spent $5.25
Step-by-step explanation:
The total cost of the apples is $5.25 if Zoe bought 1.5 pounds of apples for $3.50 per pound.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Zoe bought 1.5 pounds of apples for $3.50 per pound.
Let x be the total cost of the product:
x = 3.50x1.5
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
x = $5.25
Thus, the total cost of the apples is $5.25 if Zoe bought 1.5 pounds of apples for $3.50 per pound.

Truckco manufactures two types of trucks: 1 and 2. Each truck must go through the painting shop and assembly shop. If the painting shop were completely devoted to painting Type 1 trucks, then 800 per day could be painted; if the painting shop were completely devoted to painting Type 2 trucks, then 700 per day could be painted. If the assembly shop were completely devoted to assembling truck 1 engines, then 1,500 per day could be assembled; if the assembly shop were completely devoted to assembling truck 2 engines, then 1,200 per day could be assembled. Each Type 1 truck contributes $300 to profit; each Type 2 truck contributes $500. formulate an LP that will maximize Truckco’s profit.
Answer:
Step-by-step explanation:
Let y represent type 2 truck and x represent type 1 truck. The painting can be represented by the inequality:
[tex]\frac{x}{800}+\frac{y}{700}\leq 1[/tex] (1)
The assembling can be represented by the inequality:
[tex]\frac{x}{1500}+\frac{y}{1200} \leq 1[/tex] (2)
Also, x, y ≥ 0
The objective function is given as:
