Question

Please help me graph
x+y=2
y-x=2
my solution set is (2, 0)

Answer 1

Add the two equations to get 2y = 4 or y = 2.Put this value in equation 1 to get x +2 = 2 or, x =0.

Answer 2

find the slope
then, using the solution, graph them, given the slope of two equations.

the first equation has a negative slope therefor it's inclining on the left

the second equation is positive, therefor, it's inclining on the right side. . .
