Question

stion #2: Graph and state the coordinates of Triangle XYZ after a dilation using a scale factor 5/2 and center of dilation (-1, 1).

Answer 1

First we will determine the XYZ points

X = (1,3)

Y= (1,-3)

Z= (-3,1)

Now let's calculate the dilated points by a factor of 5/2

Remember that the mapping will be (x,y)→(kx,ky).

k = 5/2

X'Y'Z'

X' = (4,4)

Y' = (4,-9)

Z' = (-6, 1)
