find an equation of the line that passes through (2,4) and is parallel to the line 3xy=1. Write your answer in the form y=mx+b. please help!

First, find for m (slope):
3xy=1
y= 13x
y=3x1 , therefore m= 3
If lines in parallel to 3xy=1, then the slopes are the same. So, plug in to equation .
YY2= m(XX2)
y(4)=3(x2)
y+4=3x6
y=3x10
