Need help with setting up the y1= equation.

I can do the table. Just unsure how to plug in the numbers.

y = 5 + 1.24x

Step-by-step explanation:

Let x be the no. of thousand gallons

Then the cost, y, is:

y = 5 + 1.24 x

You have to pay $5 regardless of how much you order, and $1.24 each thousand gallon ( 1.24x for x thousand gallons)

Just plug in the no. of thosand gallons in place of x, y will be the cost

it should be a and d. lmk if i'm wrong xd

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
