Question

HELP!! PLEASE!

Write a function rule for the given situation. Give both the algebraic rule and the function rule.

Answer 1

`y=20x`

We know that the slope is 20 in this situation, as we can tell that 20 gallons are used every time the dishwasher is ran, therefore, everytime y increases by 1, x will increase by 20. Since the problem starts at the origin (0, 0), there is no y-intercept, so we don't have to worry about that.
