Find an equation of the line L, where L is perpendicular to y=3x and passes through the point (1,3)

Please help I'm not sure what formula to use or how to work out this problem
Answered by Steve
the slope of L is 3
so, the slope of all perpendiculars to L is -1/3

So, now you have a point and a slope.

If that doesn't tell you which form of the equation to use, there's trouble in River City.

I know how to get the slope. In my answer key it has the solution of -1\3x +10/3

What i don't get is how they got the +10/3 part
Answered by Abbi
Y= -1/3 + 10/3
