500 gallons of water is being drained at a rate of 4 gallons per hour, If y is the number os gallons of water in the tank after being drained for x hours, which equation represents the situation?

4x + y = 500

Step-by-step explanation:

Given:

Volume of water = 500 gallons

Water drained rate = 4 gallon per hour

Find:

Equation

Computation:

Total volume of water left in tank = y

Number of hour water drained = x

So,

Volume of water - Total volume of water left in tank = Water drained rate[Number of hour water drained]

500 - y = 4x

So,

Water drained;

4x + y = 500

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
