Question

triangle mnp is dilated according to the rule do1.5(x,y)→(1.5x, 1.5y) to create the image triangle mnp, which is not shown. what are the coordinates of the endpoints of segment mn? m(-6, 9) and n(4, 9) m(-6, 9) and n(3, 9) m(-2, 3) and n(7, 9) m(-2, 3) and n(1, 3)

Explanation:

Step1: Find coordinates of M and N

From the graph, assume M(-4, 6), N(2, 6).

Step2: Apply dilation rule

For M: $x' = 1.5\times(-4)= - 6$, $y'=1.5\times6 = 9$. For N: $x' = 1.5\times2=3$, $y'=1.5\times6 = 9$.

Answer:

M'(-6, 9) and N'(3, 9)
