1. Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with the origin as the center of dilation using the rule
(x, y) — (3x, zy) to create pentagon
M'N'P'Q'R'.
What is the x-coordinate of R'?

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer: it is 8

step-by-step explanation:

you know why its 8
