Only focus on one component at a time; [For example, only find the y-intercept of each situation first. Then move or
the slope.]
Practice Problems:
Compare the equation in Item 1 with the graph in Item 2.
A. Items 1 and 2 have the same rate of change,
and the same y-intercepts.
B. Items 1 and 2 have the same rate of change,
but different y-intercepts.
C. Items 1 and 2 have different rates of change,
but the same y-intercepts.
D. Items 1 and 2 have the different rates of change,
and different intercontr
