Finding the Slope of a Line from the Slope Formula:

- Label one point as (x
_{1}, y_{1}) - The other point becomes (x
_{2}, y_{2}) - Plug into the slope formula:
- We are finding the change in y-values over the change in x-values
- We sometimes hear the phrase "rise over run"

- Simplify and use m to label the slope of the line passing through the given points

Finding the Slope of a Line from Slope-Intercept Form:

- Solve the given equation for y
- This means y is isolated on one side of the equation
- We obtain the form: y = mx + b

- The slope is given as m, the coefficient of x
