An equation to represent the relationship between miles driven (y) and gallons of gas (x) used is [tex]28=ky[/tex]
Given the following data:
Distance = 28 miles
To write an equation to represent the relationship between miles driven (y) and gallons of gas (x) used:
In this exercise, we would assign a variable to the parameters stated in the question in order to write an equation to represent the relationship between miles driven (y) and gallons of gas (x) used by Weston’s car during the trip.
Also, the amount of gas used up by a car is directly proportional to the distance traveled by the car. Mathematically, this is given by this expression:
[tex]x\; \alpha \;y\\ \\ x=ky[/tex]
Substituting the given parameters into the formula, we have;
[tex]28=ky[/tex]
Note: k is the constant of proportionality.
