Explain to me in words how you would find the slope of this line. And explain how you got the answer

-1/3

Step-by-step explanation:

Okay so we're going to start with the one point and go down once, rise, and go over 3 times, run. To find slope you divided the rise by the run so it would be -1/3

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

answer is x<
