Afarmer has 60 bales of hay stored in his barn. he feeds his cows 4 bales each day. which graph represents the number of bales in the barn, y, after feeding his cows for x days?

The required equation is  and graph of this equation is shown below.

Step-by-step explanation:

Let y be the number of bales in the barn after feeding his cows for x days.

It is given that a farmer has 60 bales of hay stored in his barn.

Initial number of bales = 60

He feeds his cows 4 bales each day. It means number of bales decrease by 4 bales per day.

Slope = -4

The slope intercept form of a line is

where, m is slope and b is y-intercept or initial value.

Substitute m=-4 and b=60 in the above equation.

The y-intercept of the graph is 60.

The table of values is shown below

   x               y

   0             60

  15              0

Plot these these points on coordinate plane and connect them by a straight line.

The required graph is shown below.
