Write an equation in slope-intercept form for the line with slope -4 and y-intercept -1

y=-4x-1

Step-by-step explanation:

slope = m

y-intercept =b

y=mx+b

y= -4x -1

y=-4x-1

Step-by-step explanation:

The slope-intercept form is as follows "y=mx+b"

In this case, m, your slope, is -4.

Your b-value, is the y-intercept, -1.

Therefore your equation is y=-4x-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

answer: i think it is (1,-2)
