Question

Can Anyone Help Me With This 16Question Test !?!?!

Answer 1

Question 1


What are the slope and the y-intercept of this equation:

y = -4x - 7
A.

Slope = 4, y-intercept = 7
B.

Slope = -4, y-intercept = -7
C.

Slope = 4, y-intercept = -7
D.

Slope = -4, y-intercept = 7
Question 2


What is the slope-intercept form of this equation?

4x + 2y = 12
A.

y = -2x + 6
B.

2y = -2x + 12
C.

4x = -2y + 12
D.

y = 2x + 6

Answer 2

y = mx + b

m = slope
b = y intercept

Answer 3

I think D

Answer 4

@INeedSomeHelp! you have to post each question one at a time

Answer 5

The 7 is not positive its negative okay

Answer 6

I think 1 is {D} and I think 2 is {A}

Answer 7

the first one is b

Answer 8

second one is correct :) nice job

Answer 9

Solve the equation for y:

10x + 5y = 30
A.

10x = -5y + 30
B.

y = -10x + 30
C.

y = -2x + 6
D.

y = -2x + 30

Answer 10

subtract the 10x from both sides

Answer 11

then you have 5y = -10x + 30 and you can divide by 5

5y/5=y -10x/5= -2x 30/5=6
y = -2x + 6

Answer 12

Thank youu ,

Which is an equation in point-slope form for the given point and slope?

Point: (2, -5) Slope: -4/5

A.

y - 5 = -4/5(x + 2)
B.

y + 5 = -4/5(x -2)
C.

y = -4/5 x - 2
D.

y - 2 = -4/5(x - 5)

Answer 13

okay so point slope form is y - y1= m(x - x1)

Answer 14

y - (-5)= -4/5(x - 2)

Answer 15

y + 5 = -4/5x and -4/5(2)

Answer 16

y + 5 = -4/5x - 8/5

Answer 17

So its {B} ? and


What is the slope of the line that passes through these 2 points?

(-2,3) and (2, -5)
A.

2
B.

-2
C.

1/2
D.

-1/2

Answer 18

Yea b sorry i kept going

Answer 19

slope = y2-y1 / x2 - x1

Answer 20

-5 - 3 / 2 - (-2) =?

Answer 21

For some reason I think its a if not I think B

Answer 22

-5 -3 is -8 and 2 - (-2) is 2 + 2 which is 4 so -8/4 is -2. its not a its b

Answer 23

What does the slope of a line represent?
A.

Where the line crosses the y axis
B.

The ratio of the change in y values over the change in x values
C.

The ratio of the change in x values over the change in y values
D.

The height of the line

Answer 24

what do you think it is

Answer 25

C

Answer 26

correct :) see you know it

Answer 27

i will still be online but ihave to go to a class so i might not be able to answer ill try tho
