Answer by josgarithmetic(39618) (Show Source): You can put this solution on YOUR website!
Y = X + 1
slope , y-intercept (0,1)
Y = -X - 1
slope , y-intercept (0,-1)
That information from the equations lets you make the graph.
Calculating for y and x, you have two formulas for y which should be equated.
and you can find y using either of the given equations.

i do not understand how to figure out the value for x and y in these equations.
Y = X + 1
Y = -X - 1

Hello,
it is very simple.
Since the left sides are identical, it means that the right sides are equal, too. It gives you an equation
x + 1 = -x - 1.
Simplify and solve:
x + x = -1 - 1,
2x = -2,
x = -1.
Hence, Y = X + 1 = (-1) + 1 = 0.
Answer. The solution is x = -1, y = 0.
