    Find the midpoint between (–1, 2) and (3, –6). Apply the Midpoint Formula: midpoint is (1, -2) So the answer is P = (1, –2). Technically, the Midpoint Formula is the following: [(x_1 + x_2)/2 , (y_1 + y_2)/2] But as long as you remember that you're averaging the two points' x- and y-values, you'll do fine. It won't matter which point you pick to be the "first" point you plug in. Find the midpoint between (6.4, 3) and (–10.7, 4). Apply the Midpoint Formula: P = (-2.15, 3.5) So the answer is P = (–2.15, 3.5) Find the value of p so that (–2, 2.5) is the midpoint between (p, 2) and (–1, 3). I'll apply the Midpoint Formula: Copyright © Elizabeth Stapel 2000-2011 All Rights Reserved ( [p - 1]/2 , 2.5 ) = ( -2, 2.5 ] This reduces to needing to figure out what p is, in order to make the x-values work: p = -3 So the answer is p = –3.
