I am stumped again.

Find the equation of line L in standard form. L is parallel to y=1/3x.

I am not sure why I am thrown off. It shows line L with a point of (2,4)

I have y=-x+6 and I know that can't be correct because the slopw is 1/3 so is it y=-1/3x+6

I am really confused.

Please help to see what the answer is and why so that I can understand.

hi Mom,

To be parallel it must have the same gradient, ie. 1/3

So y = (1/3)x + something..

(2,4) => 4 = (1/3)2 + something => something = 4 - 2/3

Well, we know that it must be of the form y=1/3 x+n, so we just substitute x=2 and y=4 and solve for n. Can you do that?

simple, just note that it goes thru (0,0), so subtract from y and and x the 2 and the 4.

(y-4) = (1/3)(x-2)

that's all there is to it.

very simple.

the end.

lol.
