Question

A Line Segment has the points (1,-2), and (3,-2). What are the new points after its dilated by a scale factor of 3/2 or 1.5?

Answer 1

Answer: (1.5,-3) and (4.5, -3)

Explanation:

The dilation rule to dilate a point (x,y) by a scaler factor of k is given by :0

`(x,y)\to (kx,ky)`

Given: A Line Segment has the points (1,-2), and (3,-2).

Scale factor = 1.5

Then, the new points after dilation will be :

`(1,-2)\to(1.5*1,\ 1.5*-2)=(1.5,\ -3)`

`(3,-2)\to (1.5*3,1.5*-2)=(4.5,\ -3)`

Hence, the new points after its dilated by a scale factor of = (1.5,-3) and (4.5, -3)
