Find the equation of the line from the given information.

1. *m* = 3 and *b* = -4

2. *b* = 5 and *m* = -1/2

3. *m* = 6 and a point on the line is (3, -4)

4. *m* = -5/3 and a point on the line is (4, 2)

5. *m* = 4/5 and a point on the line is (0, 2)

6. *m* = -3/2 and a point on the line is (-2, -7)

7. *m* = 1 and a point on the line is (4, 0)

8. *m* = -3 and a point on the line is (5, -8)

9. *m* = -1/5 and a point on the line is (1, -8)

10. How could you find the equation of a line if you were given two points on the line and nothing else?

(Hint: What information do you need and how can you get it from the two points?)
