1. x midpoint: (-9+4)/(2) = -2
2. y midpoint: (3+7)/(2) = 5
3. The midpoint is (-2,5)
1. X(0,0) --> X'(3,-5).
To go from (0,0) to (3,-5), you must go to the right 3 and down 5.
I cannot answer 2 or 3, as rotations are not my strong suit.
If 1 inch equals 20miles then 8 inches equals 20 x 8 = 160 miles.
