Ill give the brain my duuudes plot the x- and y-intercept to graph this equation y=-1/2x-3. plz plot on graph : ))

i have attached my graph

hope this helps

Step-by-step explanation:

Check out the attached image below for the x and y intercepts, along with the line that goes through the two points.

To find the y intercept, plug in x = 0 and simplify

y = (-1/2)*x - 3

y = (-1/2)*0 - 3

y = 0 - 3

y = -3

In short, the y intercept is simply the constant at the end as the variable term goes away when x = 0. This is represented by the point (0,-3) as shown in red in the attached image below. This is where the graph crosses the y axis.

--------

To get the x intercept, we do the opposite as before. We plug in y = 0 and solve for x

y = (-1/2)*x - 3

0 = (-1/2)*x - 3

3 = (-1/2)*x

(-1/2)*x = 3

x = -2*3

x = -6

When x = -6, y = 0. So the x intercept is the point (-6,0) as shown as the blue point in the attached image below.

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
