Can somebody please help me!! A: They are useful way to make a figure larger or smaller.

B: They sometimes require changing the shape of a figure.

C: They can help you see if two figures are congruent.

D: They involve spinning a figure around the origin.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

answer:

c) the x-coordinate of the center of the circle increases by 3
