-Graphing Linear equalities with slope and y-intercept-

Answers

Answer 1

The slope is equal to -2.

The y-intercept is equal to 1.

The equation is y = -2x + 1.

What is the point-slope form?

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

m represents the slope.x and y are the points.

At point (-1, 3), an equation of this line can be calculated by using the point-slope form:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 3 = (-1 - 3)/(1 + 1)(x + 1)

y - 3 = -2(x + 1)

y = -2x - 2 + 3

y = -2x + 1

Answer 2

X=2
Y=-4
Ok so you y interpret is going to be -2 because that’s were the line cross
I’m not sure what the slope is though

Answer:

1. 3 students

2. 1/10

Step-by-step explanation:

if there are 30 kids in the class, and 2/5 are in band that means 12 students are in band

30÷5 =6

6×2= 12

if 1/4 of those 12 play the saxophone, then 3 of those students play the saxophone.

12÷4= 3

3 is 1/10 of 30, which gives you the answer to the second question.

Answers

Answer:

Step-by-step explanation:

There is 8 on one side and 2a + 2 on the other so we can eliminate answer D.
8=2a+2

We take away 2 from both sides getting a on one side. So 6=2a. To find a we do the inverse way to solve the equation. To get 6 we multiply "a" by 2. To get "a" we dp 6/2 = 3. boom a=3 so C is your answer

Answer:
C
Explanation:
The answer is 3 because if one side is 8 and you have 2 on one side you do 8-2 which is 6. Since you have 2 a’s you do 6 divide by 2 which is 3. This means that the answer is c

How many seconds would it take to fill a water balloon with a pint of water if the hose dispenses water at the rate of 20 pints/minute?
seconds?

Answers

Answer:

3 seconds

Step-by-step explanation:

1 minute = 60 sec

fill rate = 20 pints/60 sec = 0.33 pints/sec

t = time

(0.33 pints/sec)(t) = 1 pint

t = (1 pint) / (0.33 pint/sec) = 3 sec

Question
On a piece of paper, use a protractor to construct right triangle ABC with AB=3 in., m∠A=90°, and m∠B=45°.

What statement is true about the triangle?

A/1).AC=3 in.
B/2).BC=3 in.
C/3).BC=6 in.
D/4).AC=6 in.

Answers

Answer:

AC=3 in.

Step-by-step explanation:

It is given in the figure attached, in Δ ABC

∠ A = 90°

m∠B = 45°

AB = 3 in.

We have to find all sides of the triangle given

we will apply sine in Δ ABC to find the measure of AC

sinB =

Now by cross multiplication

BC = 3√2 in.

Now by Pythagoras theorem

BC²= AC² + AB²

(3√2)² = AC² + 3²

18 - 9 = AC²

AC = √9 = 3

Now we come to the options you have mentioned

AC = 3 in. is the correct answer.

B(-3,-11)

Answers

Answer:

Step-by-step explanation:

Solution

Distance between two points =

(x 2−x 1) 2+(y 2 −y 1) 2

Given, one point =(2,−3)

Let, other point =(10,b)

absicca is x cordinate

(10−2) 2+(b+3) 2=108 2+(b 2+9+6b)=10

Squaring both sides, we get

64+b

+9+6b=100

(b+3)

=36

∴ b+3=6 and b+3=−6

∴ b=3 and b=−9

Your answer would be A(-3,-3)

The easiest way to solve this problem would be to graph it. Graph each of the points them count the units or squares between each point. Whichever one is only 8 units is the answer. Hope the image helps.
