Question

can someone hlep me solve this by graphing?
x-y+3=0
x+y-1=0

Answer 1

First, solve for y = mx+b, the standard equation for a line.

x - y + 3 = 0
-y + 3 = -x
-y = -x -3
Multiply by -1 to get rid of the negative
y = x + 3


Now solve for y in the next equation
x + y -1 = 0
y - 1 = -x
y = -x +1

Now, graph these two equations and see where the lines cross. That point is your answer.

Answer 2

When you graph it, your solution should be (-1,2)

Answer 3

or x = -1 and y = 2
