What is the scale factor in the dilation if the coordinates of A' are (-7, 6) and the coordinates of C’ are (-4.3)? a. 1/3
b. 1/2
c. 2
d. 3

  a.  1/3

Step-by-step explanation:

For dilation about the origin, the ratio of any pair of corresponding coordinates will give you the scale factor:

  A'y/Ay = 6/18 = 1/3

The scale factor is 1/3.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

i think the answer is 90 hope this
