A. Slope-Intercept Form of a Linear Equation is y = mx + b
- "m" represents the slope.
- "b" represents the y-intercept.
B. How to Graph Using y = mx + b
- Solve the equation for y.
- Determine the slope and y-intercept.
- Graph the y-intercept.
- Use the movements of slope (or rise/run) to graph more points begainning at the y-intercept.
- Connect the points with a straight line and arrows on each end.
- Label the line with its equation.
