1. Graph the following linear equations on the grid. The equation y = x has been graphed for you. For
each new equation explain what the number 3 does to the graph of y = x. Pay attention to the
y-intercept, the x-intercept, and the slope. Identify what changes in the graph and what stays the
same.
a.
y = x + 3
b. y = x-3
c. y = 3x
2. The graph of y = x is given. (See figure 2.) For each equation predict what you think the number-2
will do to the graph. Then graph the equation.
a. y = x + (-2)
Prediction:
b. y = x- (-2)
Prediction:
c. y = -2x
Prediction:
