The document discusses the slope-intercept form of a linear equation, y=mx+b. It explains that x represents the input, y represents the output, m is the slope of the line, and b is the y-intercept. It provides instructions for graphing a linear equation in slope-intercept form, which is to first plot the y-intercept and then use the slope to rise and run to the next point, connecting the points with a line.

1. Slopey = mx + bAlgebra 1

2. Slope = = ReminderRiseRun∆ y∆ x

3. Slope – given points

4. y = mx + bThe most common form for a linear equation is called slope-intercept form.

5. y = mx + bThe most common form for a linear equation is called slope-intercept form.The equation for this form is y = mx + b.

6. y = mx + bx represents the input.

7. y = mx + bx represents the input.y represents the output.

8. y = mx + bx represents the input.y represents the output.m is the slope of the line.

9. y = mx + bx 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.
