Find the slope of the line without graphing using the 2 points below. (3 , -10) & (4 , -21)

m =

m=-11

Step-by-step explanation:

To find the slope of the line, you want to use formula . Since we are given two points, we can directly plug them in and solve.

Now, we know that the slope is -11.

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

true
