The endpoints of are A(2, 2) and B(3, 8). is dilated by a scale factor of 3.5 with the origin as the center of dilation to give image . What are the slope (m) and length of ? Use the distance formula to help you decide: .

• geometry -

The slope does not change.

Multiply all coordinates by 3.5:
A(7, 7), B(10.5, 28).

m = (28-7)/(10.5-7) =

L = Sqrt((10.5-7)^2 + (28-7)^2) =
