Question

Graph the image of the given triangle under a dilation with a scale factor of ​ −4 ​ and center of dilation ​ (0, 0) ​.

To graph the triangle, select the "Polygon" tool and draw the triangle by plotting each vertex in order until it lands back on the first vertex. Do not retrace any sides. You may use the "Move" tool to move your image if you needed.

Answer 1

The yellow outline is correct

Answer 2

See attachment

Explanation:

The coordinates of the vertices of this triangle are;

`(-2,-2),(1,-2),(1,2)`

The mapping for a dilation with a scale factor -4 about the origin is :

`(x,y)\to (-4x,-4y)`

The coordinates of the vertices of the dilated triangle are:

`(8,8),(-4,8),(-4,-8)`

We plot these points and connect them with straight lines.
