y = -2x +4 is the standard equation form in this case.
The slope of your original line is -2, and that is also the slope of the parallel line you want.
You want a line with equation y = -2x + C, where C is the constant that makes it pass though (-1, 5)
5 = (-2)(-1) + C
Solve for C and then write out your new equation
Find an equation of the line parallel to the graph of 4x + 2y = 8 and containing (-1,5)
