Question 130965
Bob has $40 to spend on popcorn and pop.  The equation 5x + 2y=40 describes the number of popcorns x and small drinks y she can buy.  Graph this function and find its intercepts.  The graph is set up with numbers 2-20 on each axis.
---------------------
5x + 2y = 40
Intercepts:
x-intercept:
Let y = 0, then x = 8
Point (8,0)
----------------
y-intercept:
Let x=0, then y = 20
Point (0,20)
