 Quadrant I; (+, +) y-axis  Quadrant II: (-, +)  Quadrant III: (-, -)  Quadrant IV: (+, -)  Origin (0,0) x-axis  Coordinate – a point  Ordered pair – (x, y)

 The distance d between two points A(x₁, y₁) and B (x₂, y₂) is:

 R(-2, 6) and S(6, -2) find the distance to the nearest tenth.

 AB has endpoints A (1, -3) and B (-4, 4). Find AB to the nearest tenth.

 Each morning Juanita takes the “Blue Line” subway from Oak Station to Symphony Station. The map shows that Oak Station is one mile west and two miles south of the City Plaza and Symphony Station is one mile east and two miles north. Find the distance.

 The coordinates of the midpoint M of AB with endpoints A(x₁, y₁) and B(x₂, y₂) are the following:

 AB has endpoints (8,9) and (-6,-3). Find the coordinates of its midpoint M.

 Find the coordinates of the midpoint of XY with endpoints X(2, -5) and Y(6, 13)

 The midpoint of DG is M(-1,5). One endpoint is D(1,4). Find the coordinates of the other endpoint G.
