Isabella has three rectangular cards that are 4 inches by 5 inches. How can she arrange the cards,
without overlapping, to make one larger polygon with
the smallest possible perimeter? How will the area of the
polygon compare to the combined area of the three cards?

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
