Best Answer

Always begin by putting your equations in slope intercept form:

x + y = 5

y = -x +5

By plugging numbers in for x, we can solve for y - we can easily find two points for this line: (0,5) and (5,0)

2x - y = 1

-y = -2x + 1

y = 2x - 1

Again, we can now easily find two points for this line: (0,-1) and (2,3)
