Lesson 2-2 Graphing on a Coordinate Plane Obj: The student will be able to graph points on the coordinate plane HWK: p 56-57 19-36 all Vocab: 1) coordinate plane 2) x-axis 3) y-axis 4) quadrant 5) x-coordinate 6) y-coordinate 7) origin

Give the coordinates and quadrant of each point. Ex 1) Point M Ex 2) Point N Ex 3) Point P M P N

Ex 4) List and explain 3 situations or careers that may use coordinates.

Graph each point on a coordinate plane. Ex 5) a) A (2, 5) b) B (2.5, 5) c) C (0, 4 1 2 ) d) D (-2.3, -3)

Distance Between Points Given two points (x₁ , y₁) and (x₂ , y₂) Horizontal distance = | x₁ - x₂ | Vertical distance = | y₁ - y₂ | Why is the | | in the distance?

Find the distance between each pair of points. (mathematically) Ex 6) a) A and B Ex 7) C and D B A D
