The slope of y = 2x- 4 is 2.
==>
The slope of new line must be 2.
y - Y = m(x - X)
m = 2
(X,Y) = (5,3)
y - 3 = 2(x - 5)
y = 2x - 7

y=2x-7
if the new equation is going to be parallel to y=2x-4 that means they must have the same slope. Well, y=2x-4 is in the form y=mx+b were m is the slop.
so substitute 5 for x and 3 for y into y=mx+b and you will get 3=2(5)+b
now solve for b and you should get b=-7
now plug be into your equation and you will be y=2x-7.
