Students will be able to graph equations of lines. Linear Functions Students will be able to graph equations of lines.
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
