The rate is 9(units of y) per (unit of x).
<span>Simplifying
graph + -1x + -9y = 8
Solving
aghpr + -1x + -9y = 8
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add 'x' to each side of the equation.</span>
8. domain=hours
range=cost
it is a function because there is a y value for ever x
9. minutes =60, 120,180, 240 (domain)
calories= 360, 720, 1080, 1440 (range)
