Dilate the Point.

Question

Dilate the point (-9,-3) with a scale factor of 3/2.

Answer 1

Assuming we are dilating with respect to the origin, then the coordinates of the dilated point are:

 

((-9)(3/2), (-3)(3/2))

 

Just multiply each coordinate by the scale factor.

Answer 2

Assuming you are dilating about the origin, you simply multiply each coordinate by 3/2.

 

since you have x- -9 and y = -3,   if you multiply each by 3/2,  you'll get:

 

x1 = -9*(3/2) = -14.5, and

y1 = -3*(3/2) = -4.5

 

(-13.5, -4.5)
