Answer 2

To dilate any point, with the origin as the center of dilation, you simply multiply each coordinate by some scale factor k

(x,y) ------> (x*k, y*k)

Answer 3

(-5,7) turns into (-18.5, 25.9)

So this means

-5*k = -18.5
and
7*k = 25.9

what must the value of k be?

Answer 4

3.7?

Answer 5

yes, so that is the scale factor
