1. Given a Bunch of Random Information About a Line Galore!!!! Created by Matt Cohen

2. m is slope b is y-intercept Slope y-intercept

3. Identify the Slope and y-intercept m = -1, b = 2 m = 4, b = 0 m = 1, b = -7 m = -2, b = 3 m = 0, b = 2 m = 2/3, b = -1/5

4. Writing Equations in Slope-Intercept Form y = mx + b Write the equation of the line that has a slope of –3 and y-intercept 4.

5. You Try a Couple! Write the equation of the line that has a slope of 1 and y-intercept –2. Write the equation of the line that has a slope of 0 and y-intercept 11.

6. Writing Equations in Slope-Intercept Form y = mx + b that has a slope of 2 and passes through the point (3, 1).

7. You Try a Couple! Write the equation of the line that has a slope of -1 and passes through (4, 3). Write the equation of the line that has a slope of 0 and passes through (-2, 5).

8. Writing Equations in Slope-Intercept Form y = mx + b that passes through (-1, 2) and (1, -6). –Find slope using –Take slope and 1 point (x, y) & plug in.

9. You Try a Couple! Write the equation of the line that passes through (1,1) and (7, 4). Write the equation of the line that passes through (-3,4) and (0,-6).

10. Writing Equations in Slope-Intercept Form y = mx + b that is parallel to y = 3x – 2 and passes through (-6, 0). Recall: Parallel lines have the “same” slope with different y-intercepts.

11. You Try a Couple! Write the equation of the line that is parallel to y = x + 4 passes through (1,-2). Write the equation of the line that is parallel to y = -2x – 1 passes through (3,1).

12. Writing Equations in Slope-Intercept Form y = mx + b that is perpendicular to y = 3x – 2 and passes through (-6, 0). Recall: Perpendicular lines have “opposite- reciprocal” slopes.

13. You Try a Couple! Write the equation of the line that is perpendicular to y = x + 4 passes through (1,-2). Write the equation of the line that is perpendicular to y = -2x – 1 passes through (3,1).
