Need help ASAP on #4

Answer:
Step-by-step explanation:
unit rate of the graph: this is the slope - slope is the rate of how steep the line is (just like the slope of a mountain, in real life)
slope/unit rate is:
where you are using points ([tex](x_{1} ,y_{1} ) and (x_{2} ,y_{2} )[/tex] . These two points that you use should be lattice points, or points that are right on the corner of a box. Pick two points on the line that go directly through a corner and insert these points onto the equation to answer the question.
Because unit rate is
we use the Y-value over the X-value (y stuff per x stuff)
our y axis for this graph is : $ (money)
our x axis for this graph is : movies
therefore, the unit rate is: $/movies (money per movie)
