1. 5.1 Finding Slope

2. Slope (m) the steepness of a line the rate of change
the ratio of change in the y-coordinates to the change in x-coordinates
the rise over the run
formula

3. Rate of Change Determine if each function is linear. Ex 1 Ex 2 x y 1 612 3 18 4 24 x y
-10 5 -2 1 6 -4 14 +6 -4 +8 +1 -5 +8 +1 +6 +1 +8 -6 +6

4. Four Types of Slope
positive
negative
zero
undefined

5. Rise over Run
Find the slope of each line.
Ex 3
Ex 4 +2 +4

6. Rise over Run
Find the slope of each line.
Ex 5
Ex 6 -2 +3

8. Find the slope of each pair of points
Ex 7 (6, 4) (3, – 1) Ex 8 (0, – 3) (6, 0) Ex 9 (2, – 3) (2, 3) Ex 10 (1, – 4) (– 2, – 4)

9. Find the coordinate, given the slope
Ex 11 (r, 6) (10, – 3);

10. Find the coordinate, given the slope
Ex 12 (6, 3) (r, 2);
