Question 285718
use the y-intercept and the slope to graph each line. 
The equations are: y = x-3 and y = x+1 I got a intersect at (2, 0) 
When I do a check I do not believe that this satisfies both equation. 
Can you detail out step by step instruction on how to solve this problem.
-----------------------
Graph y = x-3
---
y-intercept at (0,-3)
Slope is 1 so y increases 1 when x increases 1.
(1,-2)
(2,-1)
(3,0)
=================
Graph y = x+1
Y-intercept at (0,1)
Slope is 1 so y increases 1 when x increases 1.
(1,2)
(2,3)
(3,4)
==============
Note: The slopes are the same for the two equations
so the lines do not intersect.  There is no solution
for the system.
==========================
{{{graph(400,300,-10,10,-10,10,x+1,x-3)}}}
