    what is the slope you need to use to make it parallel to y=4x-2?

    no you have the info you need, for it to be parallel you use the same slope as the equation given. so what is the slope in y=4x-2?

    hint in y=mx+b, m is the slope

    yes good job, so now we have y=4x+b, lets fill in the x and y from the coordinates given.

    so then 6=4(-3)+b?

    wait do you need to find the b also? do you have to graph it?

    No, but these are the choices they gave me to choose from. x – 4y = –18 x + 4y = 18 4x – y = –18 4x + y = 18

    no no you are on the right track! now solve for b in 6=4(-3)+b

    ok now we have the slope and b value. y=4x+18, which one of the answers can be turned into this?

    no it is c, 4x – y = –18 -y=-4x-8, divide by -1 to get y by itself, y=4x+18
