In the coordinate plane, line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3). What are the slope and y-intercept of line r? A.
Line r has slope 5 and y-intercept (0, 2).

B.
Line r has slope 8 and y-intercept (0, 5).

C.
Line r has slope 8 and y-intercept (0, 9).

D.
Line r has slope 11 and y-intercept (0, 8).

step-by-step explanation:

if x = 2 you have to find x to finish the problem

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

i believe it's a.

i'm not sure on this one, most likely correct.
