Which of the following is not a correct description of the graph of the function y = -2x - 7?
the graph of the function contains the point (−2, −3), and when the value of x increases by 1 unit, the value of y decreases by 2 units.
the graph of the function contains the points (−1, −5), (2, −11), and (4, −15).
the graph of the function is a line that passes through the point (0, −7) with a slope of −2.
the graph of the function contains the points (0, −7), (1, −9), and (3, −1).

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
