Hi grettadoty,

Find the equation of line L in standard form.

I added the period to make it a sentence.

L is parallel to y = 1/3 x.

I understand this part.

Both lines are diagonal to each other

I don't know what that means.

The other points are (2, 5)

This is just one point.

I'm going to assume you want to find the equation of line L which passes through point (2, 5) and is parallel to y = 1/3 x. Am I close?

If so,

The slope of y = 1/3 x is 1/3. So this means that the slope of any line parallel to it will also be 1/3.

Now use the point-slope form of the general equation to start with, using m = 1/3 and (x1, y1) = (2, 5)

Standard Form
