A figure has vertices A(-2,5), and B(2,7). Find the coordinates A’ and B’ of the figure after dilation with a scale factor of 5.

irrational, cannot

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
