Question 1032409
{{{2x-y=4}}}
{{{-y=-2x+4}}}
{{{y=2x-4}}}


You want slope to be  same as this equation, so slope will be 2, for both lines parallel.


Plug the point coordinates into point slope form equation.
{{{y-1=2(x-5)}}}---------Do anything else you need to.



Actually, the easier and simpler way is to keep everything in standard form, as was the given equation.  Coefficients on x and y will be unchanged.
{{{2x-y=2*5-1}}}
{{{2x-y=9}}}---------------the answer.
