Question

Triangle PQR has the coordinates P(2,4), Q(-2,4), R(0,-5).

Write the coordinates of the vertices of the image of a triangle after a dilation of 2.
P' ___
Q' ___
R' ___

Write the arrow notation rule for the dilation, use (x,y) --->(___)

Answer 1

AnswerStep-by-step explanation:

dilation = multiply

so

P'= (2*2,4*2) Q'= (-2*2,4*2) R'= (0*2,-5*2)

P'=(4,8) Q'= (-4,8) R' = (0,-10)

(x,y) ----> (x*2,y*2)
