Question

A triangle has vertices A(0, 0), B, (–2, 8), and C(1, 7). What are the coordinates of the triangle after a dilation with a scale factor of 4?

Answer 1

Explanation:

mutiply x and y component by 4

A(0 , 0) = (4*0 ,,4*0)

A' = (0 , 0)

B(-2 , 8) = (-2*4 , 8*4)

B' = (-8 , 24)

C(1 , 7) = (1*4 , 4*7)

C' = (4 , 28)
