line contains points (2, 2) and (4, 1). Another line graphed in the same coordinate plane contains points (1, 2) and (3, 4). Based on the slopes of these lines, are they parallel, perpendicular or neither?

Best ResponseYou've already chosen the best response.1Yes the lines are parallel since tehy both have the same slope but like i am assuming you have to solve it not just say its parallel
