what is the slope you need to use to make it parallel to y=4x2?

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=4x2?

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

so then it would be 4??

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

would b be 6?

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

the last one i think

no it is c, 4x – y = –18
y=4x8, divide by 1 to get y by itself, y=4x+18
