The given line is AB. It means that the initial point is A and the final point is B. The formula for determining midpoint is expressed as
(x1 + x2)/2 , (y1 + y2)/2
x1 = initial value of x
x2 = final value of x
y1 = initial value of y
y2 = final value of y
From the information given,
x1 = 2, x2 = 7
y1 = 8, y2 = - 5
Midpoint = (2 + 7)/2 , ((8 + - 5)/2
Midpoint = 9/2 , 3/2
Midpoint = 4.5, 1.5
