Part a: the graph of which equation below is a horizontal line?
1) x + y =3
2) y = 3
3) x = 3
4) x/y = 3

part b: explain in 3-4 sentences why your equation in part a is a horizontal line. your answer should include at least 4 of the following words: x-coordinate, y-coordinate, ordered pair, slope, y-intercept, slope-intercept form

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
