Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.

Answer:

m = 2

Step-by-step explanation:

The given equation is :

8x – 4y - 9 = 0

The general equation of a line is given by :

y = mx+b ...(1)

here m is slope and b is y-intercept

Equation (1) can be written as :

8x – 4y = 9

Dividing both sides by (-4)

[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)

Comparing equation (1) and (2), we get :

m = 2

Hence, the slope of the line is 2.

Answer:

It could have any number as long as the slope stays the same.

Step-by-step explanation:

It could have any number as long as the slope stays the same.

For example, it could be y=x-2 or y=x+95. Just as long as the x and y are the same.

Answer:

  (a), (b), (c) are non-proportional

  (d) is proportional

Step-by-step explanation:

An equation or graph with a non-zero y-intercept is non-proportional. That is true for (a), (b), (c).

The table of (d) is proportional, with a constant of proportionality of 6.5.

Comment on (c)

In a proportional relation, price would go up with quantity, not down. If the prices both end in 9, one cannot be double the other, as would be required for the price of a gallon to be proportional to the price of a half-gallon.

Answer:

10.53%

Step-by-step explanation:

The first step is to divide 2 by 19 to get the answer in decimal form: 2 / 19 = 0.1053 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.1053 * 100 = 10.53%

Answer:

11%

Step-by-step explanation:

Divide 2 by 19 and then move the decimal place twice to the right. It should be 10.5 but if rounded it becomes 11 so 11%

Answer:

hope ithelps :)

Step-by-step explanation:

1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.

And horizontal lines go through the y-axis and have equations of y= a #

2)the point on the vertical line is (4,-5), it has a y-value of -5

****Every y value on a horizontal line will be the same

so the equation for a perpendicular line would be y= -5

The solution to the equation given as 2x - 3 = 3 is  x = 3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The equation is given as

2x - 3 = 3

The above equation is a linear function

So, we plot a linear equation (see attachment)

On the attached graph, we can see that the solution is a vertical line that passes through x = 3

Hence, the solution to the equation given as 2x - 3 = 3 is  x = 3

Answer:

hey hi what's up ?...........

Step-by-step explanation:

Use the y=mx+b reference

the b refers to the y intercept which in your case is -4

so on the graph you would put -4 on the y line so at (0,-4)

Then the m or the slope which is 1.2 means from the point (0,-4) you move 1.2 units up and 1 unit to the right forever to create your line so you continuously move 1.2/1 and -1.2/-1

The required, graph of the linear equation y = 1.2x-4 is shown in the image attached below.

To graph the equation y = 1.2x - 4:

The graph of Y = 1.2x - 4 will be a straight line that passes through the points (0, -4) and (1, -2.8), and it will continue infinitely in both directions. The line will slope upwards from left to right with a slope of 1.2.

Step-by-step explanation:

Given that :

Cost of speaker = $22

Cost per song = $1.25

Sales tax rate = 7.5%

Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)

Expanding the expression :

Answer:

(2 n)/3-2/3 = n/6+4/3

(2 n)/3-2/3 = (2 n-2)/3:

(2 n-2)/3 = n/6+4/3

Put each term in n/6+4/3 over the common denominator 6: n/6+4/3  =  n/6+8/6:

(2 n-2)/3 = n/6+8/6

n/6+8/6 = (n+8)/6:

(2 n-2)/3 = (n+8)/6

Multiply both sides by 6:

(6 (2 n-2))/3 = (6 (n+8))/6

6/3 = (3×2)/3 = 2:

2 (2 n-2) = (6 (n+8))/6

(6 (n+8))/6 = 6/6×(n+8) = n+8:

2 (2 n-2) = n+8

Expand out terms of the left hand side:

4 n-4 = n+8

Subtract n from both sides:

(4 n-n)-4 = (n-n)+8

4 n-n = 3 n:

3 n-4 = (n-n)+8

n-n = 0:

3 n-4 = 8

Add 4 to both sides:

3 n+(4-4) = 8+4

4-4 = 0:

3 n = 8+4

8+4 = 12:

3 n = 12

Divide both sides of 3 n = 12 by 3:

(3 n)/3 = 12/3

3/3 = 1:

n = 12/3

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

1.08 * 10^57

Step-by-step explanation:

Given that:

Number of atoms in the sun = 1.2 * 10^57

Number of atoms in the rest of the solar system = 1.2 * 10^56

About how many more atoms exist in the Sun than in the rest of the Solar System?

Subtract the number of atoms in solar system from number of atoms in sun

(Number of atoms in sun - number of atoms in rest of the solar system)

(1.2 * 10^57) - (1.2 * 10^56)

= 1.08 * 10^57 (using calculator)

Answer:

y = -2x

Step-by-step explanation

slope intercept form: y = mx + b

m is slope and b is y-intercept

1. lets find y-intercept cuz thats easiest

the line crosses (0,0) at the y-axis so there is no y-intercept

2. to find slope rise/run

we'll start at (0,0) since that's the y-intercept

3. slope is rise/run = -2/1 = -2

it's negative becuase it's going left

_____________________________________________________

another way you can find slope is by the equation y2 - y1/ x2 - x1

take 2 random points from the line, i will use (0,0) and (-2,4)

4 - 0/ -2 - 0 = 4/-2 = -2

slope is -2
