Best ResponseYou've already chosen the best response.2you want the average of the x values of the endpoints to equal the x value of the midpoint you want the average of the y values of the endpoints to equal the y value of the midpoint remember the average of two numbers is the sum of those numbers divided by 2

Best ResponseYou've already chosen the best response.2so you have the following two equations to solve: \[\frac{5+x}{2}=1 \text{ and } \frac{2+y}{2}=0\]
