Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:

y > −2x + 3

part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)

part b: is the point (−2, 3) included in the solution area for the system? justify your answer mathematically. (4 points)

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
