Question

1. The coordinates of rectangle RSTU are R(-5, 1), S(-5,3), T(4, -3), and
U(4, 1). The rectangle will be dilated by a scale factor of 2. What are
the coordinates of S'?
A (-10,-6)
B. (-5, 1.5)
C. (2.5, 3)
D. (2.5, -1.5)​

Answer 1

Answer:

The coordinates of S' is (-10,6)

Step-by-step explanation:

The coordinates of rectangle RSTU are R(-5, 1), S(-5,3), T(4, -3), and

U(4, 1).

When the rectangle is dilated by a scale factor of 2.

Then the mapping will be;

$(x,y)\to (2x,2y)$

This implies that:

$S(-5,3)\to (2*-5,2*3)=S'(-10,6)$

The coordinates of S' is (-10,6)
