Help I don’t understand and I need this
Done as soon as possible

y - 7 = -1/4(x-4)

Step-by-step explanation:

point slope is y-y₁=m(x-x₁)

(4, 7) and (8, 6)

I like to put it in the slope-intercept form first

so... 6 - 7/ 8-4 = -1/4 (slope)

6 = -1/4(8) + b

6/(-2) = -2/(-2) + b

-3 = b

so... y=-1/4x + -3

plug it in to point slope form

y - 7 = -1/4(x-4)

hopefully that made sense :)

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
