The Coordinate Plane Chapter 2, Section 1 Distance Formula in the Coordinate PlaneLet P = (x, y) and Q = (x, y) be any two points in the coordinate plane. Then the distance between P and Q, denoted d(P, Q), is given by the distance formulad(P,Q)=(xx)²+(yy)²d(P,Q)=(xx)²+(yy)²Example 1: a)Find the distance between the points (45,5 ) b)Find the distance between the points on the graph.
Midpoint of a Line segmentThe midpoint is halfway between the two endpoints.Its x value is halfway between the two x values
