GRE 504: Find the midpoint of a line segment* GRE 603: Use the distance formula

 The midpoint is the middle of two points on a coordinate plane.  To find the midpoint, you would find the average of the x and y coordinates, or… x 1 + x 2 2 y 1 + y 2 2 (, )

Find the midpoint of the coordinates: (2, 4) & (6, 12) (x 1, y 1 ) (x 2, y 2 ) (), () , (4, 8) This is the midpoint! I remember this!

Identify the points! (5, 3) and (-3, -3) Use the formula! (, ) (, ) (1, 0). Now plot it!

Identify the points! (2, 8) and (-5, -5) Use the formula! (, ) (, ) (-1 ½, 1 ½ ). Now plot it!
