Question

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 8 and y-intercept (0, 9).

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

C.
Line r has slope 5 and y-intercept (0, 2).

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

Answer 1

Answer:

im not that smart but

Step-by-step explanation:

Given that In the coordinate plane line p had slope 8 and y intercept (0,5).

Hence equation of line p is

y = 8x+5 (slope intercept form)

When we dilate p by a factor of 3, we have

we find that slope would remain the same but the y intercept would become 3 times.

Hence new line would be

y = 8x+15

Slope = 8 and y intercept = 15

This line will be parallel to original line.
