Graphing Linear Functions There are several ways to graph linear functions: Making a table, graphing the points, and drawing a line through them. Using the two intercepts. Using the slope and the y-intercept. Using a point and the slope. FHS Functions

Make a Table Graph this equation: Make a Table: -1 -1 1 1 3 x y y x x y -1 1 -1 1 3 FHS Functions

Two Intercepts Graph this equation: Step 1: Find the x-intercept. Let y = 0, then Step 2: Find the y-intercept. Let x = 0, then Step 3: Draw a line through the two points. x y Insert examples 2 -4 here. FHS Functions

Slope and y-intercept Graph this equation: x y Graph this equation: Step 1: Graph the y-intercept (0, -2) Step 2: Use the slope to find the next point. Step 3: Draw a line through the two points. FHS Functions

Point and Slope Graph the line that passes through the point (-2, 1) x y Graph the line that passes through the point (-2, 1) and has the slope of Step 1: Graph (-2, 1) Step 2: Use the slope to find the next point. Step 3: Draw a line through the two points. FHS Functions
