Question

Find the slope of the line through each pair of points. Show your work on separate paper.

1. (0, 1) and (3, 0)
2. (-3,-2) and (1,6)
3. (4, -1) and (-2,-3)
4. (3,-5) and (1, 2)
5. (-3, -3) and (-1, -3)
6. (2, -8) and (2, 4)

Answer 1

equation of slope (m) = x2 - x1 / y2 - y1

1. 3-0/0-1 = 3/-1
m = 3 / -1

2. 1-(-3)/ 6-(-2) = 4/8 = 1/2
m = 1/2

3. -2-4/-3-(-1) = -6/-2 = 3
m = 3 or 3/1

4. 1-3/2-(-5) = -2/7
m = -2/7

5. -1-(-3)/-3-(-3) = 2/0 = undefined
m = undefined

6. 2-2/4-(-8) = 0/12 = 0
m = 0
