1. Example 1 Find the intercepts of the graph of. Finding Intercepts 2 1 y = x – 5 2 1 0 = x – 5 2 1 5 = x 10 = x STEP 1 Let 0 and solve for x to find the x -intercept. = 2 1 y = x – 5 y

2. Example 1 Finding Intercepts STEP 2 Let x 0 and solve for y to find the y -intercept. = 2 1 y = x – 5 ANSWER The x -intercept is 10 and the y -intercept is 5. The graph of the equation crosses the x -axis at 10, 0 and the y -axis at 0, 5. () () – – 2 1 = – 5 () 0 y = – 50 y = – 5 y

3. Example 2 Using Intercepts to Graph a Line Graph the line with an x -intercept of 3 and a y -intercept of 2. – The x -intercept is 3, so plot the point 3, 0. The y -intercept is 2, so plot the point 0, 2. Then draw a line through the two points. – – () ()
