Johnny is filling an empty 4-gallon bucket with water at a constant rate. There are 2.4 gallons of water in the bucket
after filling the bucket for 6 minutes. At what rate, in
gallons per minute, is Johnny filling the bucket?

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

What is the question?
