Question

PLEASE ANSWER QUICKLY!!! PLZZZZZ!!!!!!!

Answer 1

`y=-(1)/(20) x + 20`

Explanation:

The slope equation is always
`(rise)/(run)`. In this case, the gallons went down by 1- so we can call the rise -1. When it went down by 1, the miles went up by 20- so we can call the run 20. This gives us a fraction (the "m" value) to put in the slope equation
`y=mx+b`. To find the y intercept (the "b" value), you find out what y is when x = 0, which is given in the chart: 20.

Answer 2

Explanation:

each 20m miles takes 1g gallon.
