Would have been nice to have some data
Your graph would have the temperature on the x-axis
and the number of cups on the y-axis.
Your graph would consist only of the part of the x-y plane that lies above
the x-axis, since you can't have a negative number of cups.
your graph would be a line crossing the y-axis and it would lean to the left, that is, it would have a negative slope.
e.g.
suppose they sold 25 cups when the temperature was 5° C, but only 5 cups when it got
hot at 30° C.
plot (5,25) and (30,5) and join with a straight line. (let each unit on the graph represent a
magnitude of 5)
