Question

A tank is being filled with gasoline at a rate of 4.5 gallons per minute. The gas tank contained 1.5 gallons of gasoline before the filling began. Write an equation in standard form to model this linear situation.

Answer 1

Answer:

4.5x - y = -1.5

Step-by-step explanation:

y - total

x - minutes

finding the slope intercept form is way easier

slope intercept form: y = 4.5x + 1.5

now, just put it into standard form:

Ax + By = C

4.5x - y = -1.5

remember that x in standard form can't be negative
