  1. 3-7 Equations of Lines in the Coordinate Plane *I can graph and write linear equations.

  2. slope sloped sloping

  3. 3 7 5 2 4 3

  4. Slope-intercept form 3/1 0 3 1

  5. -1 2 y = mx + b 2 y = (-1/2)x + 2

  6. point-slope form Substitute Simplify

  7. y – 5 = (6/5)x – (18/5) y + 1 = (6/5)x + (12/5) y = (6/5)x – (18/5) + (25/5) y = (6/5)x + (12/5) - (5/5) y = (6/5)x + (7/5) y = (6/5)x + (7/5)
