Mr Jenkins is tiling a square floor. He uses 196 square tiles.
Work out how many tiles are in each row.

I believe it’s 49. because you would divide the sides of a square which is 4 by how many square tiles he uses which is 196.

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
