For each equation, solve for y and place the equation into y=mx%2Bb form (slope intercept form)

x + 8 = y

y = x + 8

The equation is in y=mx%2Bb form where m = 1, b = 8. The slope here is 1.

-------------------------------------------------------

y - x = -4

y = x - 4

The equation is in y=mx%2Bb form where m = 1, b = -4. The slope here is also 1.
-------------------------------------------------------

The two slopes are both equal to 1. So we have 2 parallel lines.
