1. Find the values for y by substituting 1, 3, 5, and 7 for x. 1, 3, 7, 11 1. y = 2x – 3 Bell Work

2. I can… graph points and identify parts of the coordinate plane. Today’s learning target:

3. Vocabulary coordinate plane x-axis y-axis quadrant x-coordinate y-coordinate origin

4. x-axis Vocabulary: y-axis origin (0, 0) quadrants III IIIIV Coordinate plane

5. Ex. 1 Point J is __________________ (0, 2); no quadrant Point M is _________________ (2, 0); no quadrant Point K is __________________ (–3, 4); Quadrant ll Point P is _________________ (–3, –2); Quadrant lll x y J P K M Give the coordinates and quadrants of each point.

6. (2, 3) ‏ x y origin (2, 3) ‏ move right 2 units move up 3 units (0, 0) ‏ Quadrant I Quadrant II Quadrant III Quadrant IV Not in your notes, just an example:

7. Ex. 2 Graph each point on the coordinate plane. A. A(3, 4) ‏ right 3, up 4 B. B(4, 0) ‏ right 4, up 0 C. C(–4, 4) ‏ left 4, up 4 D. D(–1, –3) ‏ left 1, down 3 x y A B D C

8. Ex. 3 Graph each point on the coordinate plane. E. A(2, 4) ‏ right 2, up 4 F. B(2, 0) ‏ right 2, up 0 G. C(–2, 4) ‏ left 2, up 4 H. D(–1, –1) ‏ left 1, down 1 x y E F H G

9. Ex. 4 x y = |–3| Distance = |–1 – (2)| M(1, 3) ‏ Find the distance between each pair of points. A. K and L Use the x-coordinates. L(2, –1) ‏ N(1, –3) ‏ K(–1, –1) ‏ = 3 The points are 3 units apart.

10. Ex. 5 x y = |6| Distance = |3 – (–3 )| M(1, 3) ‏ Find the distance between each pair of points. A. M and N Use the y-coordinates. 0 L(2, –1) ‏ N(1, –3) ‏ K(–1, –1) ‏ = 6 The points are 6 units apart.

11. Ex. 6 Be careful, the scale changed! x y = |–8| Distance = |–2 – (6)| B(6, 4) ‏ Find the distance between each pair of points. A. A and B Use the x-coordinates. 0 2 4 6 8 10 2468 2 4 6 8 6428 C(4, –2) ‏ D(4, –8) ‏ A(–2, 4) ‏ = 8 The points are 8 units apart.

12. Ex. 7 Be careful, the scale changed! x y = |6| Distance = |–2 – (–8)| B(6, 4) ‏ Find the distance between each pair of points. B. C and D Use the y-coordinates. 0 2 4 6 8 10 2468 2 4 6 8 6428 C(4, –2) ‏ D(4, –8) ‏ A(–2, 4) ‏ = 6 The points are 6 units apart.
