the perimeter p of a regular hexagon varies directly with the length l of one side of the hexagon. what is an equation that relates p and l? what is a graph of the equation?

P = 6L
straight line graph from 0,0 to 1,6; 2,12; 3,18 and beyond

P=6l. Think about it, a hexagon has 6 sides, so the length of one side, times 6, would equal the perimeter.
The algebraic expression would be y=6x
