What is the midpoint of the line segment with endpoints (-1, 7) and (3, -3)?

midpoint = (x1+x2)/2 , (y1+y2)/2

             = (-1+3)/2 , (7+(-3))/2

              = 2/2 , 4/2

              = 1,2

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
