Berto has $12 to put in his car. if gas costs $3.75 per gallon, which ordered pair on the graph of the line relating number of gallons of gas

(x, y) is the ordered pair or the point of the line. The given problem is an example of a linear graph and its ordered pair represents (amount, number of gallons).

(3.75, 1) is one of the ordered pairs of the graph since $3.75 is the amount that you paid in 1 gallon of gas.

Moreover, $12 is the amount that Berto paid for the gas, we will divide it to $3.75 per gallon in order to get the number of gallon that is put in his car.
Solution: $12 / $ 3.75 per gallon= 3.2 gallons.

Therefore, another ordered pair on the graph of the line relating number of gallons of gas is (12, 3.2) since $12 is the amount that you paid for 3.2 gallons of gas.
