What are the coordinates of the midpoint of the line segment with endpoints r(4, -7) and s(-3, 5)?

  (1/2, -1)

Step-by-step explanation:

The midpoint is the average of the end points:

  M = (R + S)/2 = ((4, -7) + (-3, 5))/2 = ((4-3)/2, (-7+5)/2) = (1/2, -2/2)

  M = (1/2, -1)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
