can i have help pls its saying the graph of a red line but its asking for What is the equation of the graph shown? but it goes up to -4 pls pls pls help me

I'd need to see the graph but if that's the problem just extend the line. You're practising y = mx + b right?

The easiest way to find the equation is to evaluate the slope. Rise over run will tell you how steep the incline is ams then you can just plug the numbers into the equation.

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
