You drive a car that holds 15 gallons of gasoline. Your car uses 0.03 gal per mi. Which equation best represents this information?
y = 0.03x + 15
y = 0.03x  15
y = 0.03x + 15
y = 0.03x  15

Best ResponseYou've already chosen the best response.0no but im using y=mx+b which means m=what could change which is .03 and then b=15 because it is your priginal so shouldnt it be y=.03x+15

Best ResponseYou've already chosen the best response.1what is slope of a line or any function y=f(x)...it is m=dy/dx i.e rate of change of y wrt x and here rate of change of y i.e fuel is negative w.r.t x...now is it better
