Question

iangle ABC will be dilated according to the rule
D Subscript F, 0.25(x,y), where point F is the center of dilation.

On a coordinate plane, triangle A B C has points (negative 5, negative 3), (negative 5, 1), and (1, negative 1). Point F is at (3, 1).

What will be the coordinates of vertex A' of the image?

(-8,-4)
(-2,-1)
(0, 0)
(1, 0)

Answer 1

A = (-5,-3). Vector FA = A - F = (-5-3, -3-1) = (-8,-4). Scale by 0.25: 0.25(-8,-4) = (-2,-1). Add to F: F + (-2,-1) = (3-2, 1-1) = (1,0).

So A' = (1, 0).
