To find the midpoint, you add both numbers together and divide by 2. Therefore, (-8+x)/2=1 and (3+y)/2=7 with x being the x value of Q and y being the y value. Solving for x, we can multiply both sides by 2 to get -8+x=2 and adding 8 to both sides to get x=10. Similarly, for y, we can multiply both sides by 2 and then subtract 3 to get y=11, making our point (10,11)
