What’s point B’
What’s point C’
After being dilated by a scale factor 1.5?

Given:

The given figure is dilated by a scale factor 1.5.

To find:

The coordinates of B' and C'.

Solution:

If a figure is dilated by a scale factor k at point (a,b), so the rule of transformation is

From the given figure it is clear that A(3,-3), B(-2,2) and C(-3,-5).

The figure is dilated by a scale factor 1.5 at point A(3,-3), so the rule of transformation is

Using this rule, we get

And

Therefore, the coordinates of B' and C' are B(-4.5,4.5) and C'(-6,-6).

ummm seems that u didnt post the attachement !

it is x=-4
