Answer:
the distance is 15
Step-by-step explanation:
because if we take away the negative on the -10 and make it positive 10 and add 5 it would be 15 spaces
To find the slope take your points, they should be (x1,y1) (x2,y2), proceed to subtract y2-y1 over x2-x1. after you calculate that simplify and put it in y=mx+B (the slope goes in the m position and x is usually left open)
I would say smaller than because you would be dilating the image by a number less than 1, which is making the image smaller.
