Step-by-step explanation:
To find the midpoint, you can think of it logically or use the formula. I will explain logically. To do this, first find the distance between the x values and the y values. The distance in x values is 4 and the distance in y values is 2. Then to get the middle, you should divide each by 2 and then add those values to the one that is lower and more onto the left so you get the midpoint as (-5,7)
