Question

Dilate the following points by each scale factor (k) provided. P(3, 4) by k=1/2 And N(4, 15) by k=2

Answer 1

Dilations involve multiplication, so we have that the dilation with scale factor 1/2 of the point (3,4) is (1.5, 2)

$\frac{1}{2}\cdot(3,4)=(\frac{3}{2},\frac{4}{2})=(1.5,2)$

and the dilation with scale factor 2 of the point (4,15) is (8, 30)

$2\cdot(4,15)=(2\cdot4,2\cdot15)=(8,30)$
