Question 549310
Recall that if two lines are parallel, then the slope is the same 
y=2x-6
what is our slope in this line? It is 2 so the slope of the line we will end up with will also be 2.  


Subbing in our given point and the slope , we can solve for b
{{{y=mx+b}}}
{{{2=2*4+b}}}
{{{2=8+b}}}
{{{2-8=b}}}
{{{-6=b}}}


So our line is 
y=2x-6


Hopefully this helps, let me know if you are unsure about any of the steps I took.
