1. 5)Find the slope of the line passing through the two given points. a)(-3,5) and (-3,1) b)(4, 6) and (1,6)

2. Do Now 1)Find the slope of the line passing through ( 3, – 2) and (4, 5).

3. 2)The line passing through the points (2, 8) and (6, k) has a slope of. Find k.

4. 3) The line passing through the points (5, – 8) and (3, a) has a slope of 4. Find a.

5. Slope – Intercept Form y = mx + b m represents the slope of the line b represents the y-intercept The y-intercept is the point where the line crosses the y-axis.

6. 4) Write a slope-intercept equation of the line with the given slope and y-intercept. a)m = 2, b = – 3 b)m = – 4, b = 5 c)m =, b = 0

7. Write the equation of a line that has a y-intercept of -3 and a slope of -4. 1.y = -3x – 4 2.y = -4x – 3 3.y = -3x + 4 4.y = -4x + 3

8. 5) Find the slope and y-intercept for each line. a)y = 4x – 1 b) y = – x + 3 c)y = 2x – 5

9. Find the slope and y-intercept of y = -2x + 4 1.m = 2; b = 4 2.m = 4; b = 2 3.m = -2; b = 4 4.m = 4; b = -2

10. 6) Write the equation of the line.

11. Writing Equations From The Graph 1)Use two points to find the slope. 2)Look where the line crosses the y-axis. 3)Substitute into y = mx + b
