In the coordinate plane line p had slope 8 and y intercept (0,5). Line r is the result of dilating line p by a factor of 3 with (0,3) what is the slope and y intercept of line r?

Given:

Coordinate plane line P:

Slope = 8

y-intercept = (0,5)

A line (R) is the result of dilating line P by a factor of 3 with (0,3).

We have to determine the slope and y-intercept of line R.

First, we have to establish the equation of the line P:

y = mx + b

where m is the slope and b is the y-intercept

y = 8x + 5

Then, multiply the y-intercept of line P with the factor:

(0 * 3, 5 * 3)

Now, we have the y-intercept of line R: (0, 15)
