Question

Graph the image of the figure after a dilation with a scale factor of 1/2 centered at (-1, 3)

use the plolygon tool to graph the triangle by connecting all its vertices.

i need this answer really fast and will give as many points as you want idc.

Answer 1

See below.

Explanation:

The coordinates of the original triangle are at

(-5, 3), (-5, 7), and (1, 7).

Since the scale factor is one-half, you are shrinking the triangle.

The coordinates of the dilated triangle will be half-way from those points to (-1, 3).

Thus, they will be at

(-3, 3), (-3,5), and (0,5).

In the image below, the green triangle is the original.

The red triangle is the dilated figure, and the black dashed lines are the dilation rays from (-1, 3).
