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

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
