6-46.

Louis is dilating triangle *ABC* below. He multiplied each -coordinate and

*-coordinate of triangle*

*ABC*by

*6-46 HW eTool*(Desmos). Homework Help ✎

What are the new coordinates of the points?

Use the graph to find the coordinates of points

*A*,*B*, and*C*. Then multiply each value by. For example, point *A*is originally. Its new coordinates will be . Find points *B*and*C*.Graph Louis’ new triangle.

After multiplying each

-coordinate and-coordinate by, plot the new points. Describe how triangle

*ABC*changed.Its sides are twice as long and rotated

. Use the eTool below to graph Louis' new triangle.
