A delivery truck averages 15 miles per gallon of gas. The equation y = 15x can be used to model this situation, where x represents the number of gallons of gas and y represents the total number of miles.

What is the independent variable?

Four equations are shown below.equation 1: y=2*equation 2: y=2x-5equation 3: y=x2 + 6equation 4: tdentify one linear equation and one nonlinear equation from the list.why each equation you identified is linear or nonlinear.nd one nonlinear equation from the list. state a reasonlinear equation
