Hey if you are good at maths here is a riddle So you have 3 apples in a basket then you took 2 apples away from the basket, how many apples are in the basket (hint it can't be the number which has only 1 factor)​

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

Ineed with this same question!
