NOTES 4.4 Graphing lines using intercepts The x-­‐intercept is where the graph crosses the x-­‐axis. You can find the x-­‐intercept by setting y = 0 and solving for x. The y-­‐intercept is where the graph crosses the x-­‐axis. You can find the y-­‐intercept by setting x = 0 and solving for y. Find the intercepts for the equations below and use them to graph the equation. 3x + 2y = 6 1. 2. −5x + 3y = 15 3. −4x − 5y = 20 4. 7x − 2y = 14
