Find the equation given the following two points (7,19)and(9,29).

Step-by-step explanation:

29-19/9-7=5=slope

y-y1=slope(x-x1)=

y-19=5(x+7)=

y=5x+35+19=

y=5x+54

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
