1. 7-5 Graphing linear equations Objectives: Graph linear equations by using the x and y intercepts or the slope and y intercept

2. Questions What are the x and y intercepts? What equation form is it easiest to find the x and y intercepts? How do you determine the x and y intercepts? When the equation is in slope intercept form how do you easily graph the equation

3. (Intercepts are the points where the line crosses the axes) Since two points determine a line, we can use the intercepts to graph. Graph the line 2x+4y=8 Set x to 0 and solve for y. Now solve for x by setting y to 0 When the equation is in standard form (ax+by=c) complete the following:

4. When equations are in slope intercept form :y=mx+b… Identify the y intercept by setting x to “0” Plot the y intercept Identify a second point by plotting the slope. You do this by starting at your y intercept point. y=-1/3x +4
