The distance from -9 to 7 = 16 units.
Distance from -4 to 8 = 12 units.
Divide the two values and add them to the x and y values of the first set and the result will be our midpoint.
16/2 = 8. 8 + -9 = -1
12/2 = 6. 6 + -4 = 2
So our midpoint will be (-1,2)
The initial value would be 52 if she begins from where she starts measuring.
