3. “slope” 3

4. Graph the line containing the points (-4,2) and (2,-3) and find the slope.6

5. Graph the line containing the points (-4,2) and (2,-3) and find the slope.
“m” 6

6. Find the slope of the line containing (1,1) and (3,5)

7. Find the slope of the line containing (2,2) and (8,9)
2-9 = -7 = 7

8. Find the slope of the line containing (-4,-6) and (3,-2)
M= = = = 4
-4 –

9. Find the slope of the line containing (-2,3) and (2,1)

10. Horizontal line = “0” slope
What is the slope?
(-6,4)
(5,4)
Horizontal line = “0” slope

11. Vertical line = “no slope”
What is the slope?
(3,8)
(3,-2)
Vertical line = “no slope”

12. A line contains points (5, 3) and (x, 9) and has slope = 3
A line contains points (5, 3) and (x, 9) and has slope = 3. Find the value of x.
3= 3-9
5-x
3 = 6
5-x
