1. Slopey = mx + b Algebra 1

2. Slope = = Reminder Rise Run ∆ y ∆ x

3. Slope – given points

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.

10. To graph: Plot the y-intercept first.

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.
