The Coordinate PlaneChapter 2, Section 1Distance Formula in the Coordinate PlaneLet P = (x, y) and Q = (x, y) be any two points in the coordinate plane. Then the distancebetween 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)∧(−25,9b)Find the distance between the points on the graph.)
