Question

The vertices of a rectangular photo on the coordinate plane are A(0, 0), B(0, 4), C(3, 4), and D(3, 0). If you dilate the photo with a scale factor of 5/2 (five-halves), what are the coordinates of vertices A, B, C, and D?
a. A(0, 0), B(0, 2), C(7.5, 2), and D(1.5, 0)
b. A(0, 0), B(0, 10), C(7.5, 10), and D(7.5, 0)
c. A(0, 0), B(0, 10), C(13, 14), and D(4, 0)
d. A(0, 0), B(0, 5), C(4, 5), and D(4, 0)

Answer 1

Multiply each coordinate by the scale factor 5/2 and see what you get.

Answer 2

c?

Answer 3

If you multiply the coordinates of points C and D by 5/2 do you get the answer in c?

Answer 4

so what is the answr?
