Need help I don’t understand how do this

look at each equation take equation I for example y = 2x then look at each table take the x value plug it in for the equation and see if you get the y value if you don't move on. so on this instance y = 2x I'm just going to plug in 2 * -2 gives me - 4, 2 * - 1 gives me -2, 2 * 0 gives me 0, 2 * 1 gives me 2 so the answer to table c is table c matches with equation i. keep doing that on your own and you should be able to get the rest
