Triangle PQR has coordinates P(2,4),(-2,4), R(0,-6). Write the coordinates of the vertices of the
image of a triangle after a dilation of 1.5.
i will assume that the center of dilation is the origin (0,0)
so
the rule of the dilation is
(x,y) ------> (1.5x, 1.5y)
therefore
the vertices of the image are
P(2,4) ------> P'(3,6)
Q(-2,4) -----> Q'(-3,6)
R(0,6) -----> R'(0,9)
