- 2. Slope = = Reminder Rise Run ∆ y ∆ x
- 4. y = mx + b The most common form for a linear equation is called slope-intercept form.
- 5. y = mx + b The most common form for a linear equation is called slope-intercept form. The equation for this form is y = mx + b.
- 6. y = mx + b x represents the input.
- 7. y = mx + b x represents the input. y represents the output.
- 8. y = mx + b x represents the input. y represents the output. m is the slope of the line.
- 9. y = mx + b x represents the input. y represents the output. m is the slope of the line. b is the y-intercept.
- 11. To graph: Plot the y-intercept first. From that point, use the slope to rise and run to the next point.
- 12. To graph: Plot the y-intercept first. From that point, use the slope to rise and run to the next point. Connect with a line.
