This document discusses slope-intercept form for linear equations and how to use it to graph lines. It explains that in the form y=mx+b, m represents the slope and b represents the y-intercept. Examples are given of finding the slope and y-intercept from equations in slope-intercept form and using those values to graph the lines. Students are instructed to graph lines using their slope and y-intercept, finding additional points using the slope and connecting the points to extend the line.

2. When a linear equation is written in the form y = mx + b , it is in slope-intercept form. y = mx + b slope y -intercept

3. State the slope and the y -intercept of the graph of y = ½ x + 3. State the slope and the y -intercept of the graph of -4 x + 5 y = -10. You can use the slope-intercept form to graph a line quickly.

4. Graph y = ½ x – 5 using slope-intercept form. Graph the y -intercept. Using “rise over run,” graph at least three other solution using the slope. Connect the dots and extend your line.

5. Graph 3 x + y = 9 using the slope and y-intercept.
