yes the answer is c or d but one is correct tho. can i see how u solved this

anonymous · Answer

well i looked to see that for x, it is increasing by 2. and for y it is increasing by 4 then i looked at the possible answers. and y = 2x seemed reasonable. but so did y = 2x + 2. i asked for help. and the person who helped me said that they agreed with me but couldn't decide between C and D too. so i just wanted some clarification
