Chapter Four 4.1 Plotting Points on the Coordinate Plane 4.2 Graph Linear Functions Graph y = 2 Graph x = 2 4.3 Graph Functions Using Intercepts You make $16 an hour mowing lawns and $10 washing windows. You want to make $500. Write an equation that represents this. Find the x and y intercepts. Graph the function. 4.4 Find Slope and Rate of Change Checkpoint: Find the slope of the line between: a) (-3, 2) and (4, 8) b) (2, -9) and (-1, 0) c) (4, 6) and (4, 9) 4.5 Graph Using Slope-Intercept Graph the equation y – 10 = 5x – 8 4.6 Model Direct Variation Checkpoint: 4.7 Graph Linear Functions Find the value of t so that m = 1055. What does this mean? Graph the following functions. Decide whether it’s better to graph in slope-intercept or by using intercepts. Then, compare it to the parent function. y = 2x - 3 2x + y = 5 y – 1 = 0.5x + 3
