Question

How do you dilate the figure with the given scale factor?

Answer 1

To get the new points for dilation with a scale factor of 1.5, we multiply 1.5 times (x,y) the ordinated pairs of each of the vertex of the triangle.

A'

`(1.5*-4,1.5*-2)=(-6,-3)`

B'

`(1.5*-2,1.5*4)=(-3,6)`

C'

`(1.5*4,1.5*-2)=(6,-3)`

The algebraic expression is:

`(x,y)=(1.5x,1.5y)`
