Me ! i just have an hour to turn this !

-26

Step-by-step explanation:

First, find the slope using two points.

Slope formula is (y2-y2) / (x2-x1)

Using the points (34,-52) and (51,-65) substitute and solve for slope.

m= -65-(-52) / 51-34

m= -13/17

Then, use the point- slope formula, and solve for the point slope intercept form. (34,-52) is the point I used.  

y-y1= m(x-x1)

y-(-52)=(-13/17)(x-34)

y-(-52)=-13/17x+26

y=-13/17x-26 this is in the form of y=mx+b where b(-26) is the y- intercept.

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
