Question 269191
My teacher told me to graph the system of linear inequalities:
y < x+1
y >(or equal to) 3
--------------------
You have to graph the boundary of each of the inequalities.
---
1st boundary
y = x+1
Graph that as a dashed line because it is not part of the solution.
{{{graph(400,300,-10,10,-10,10,x+1)}}}
Shade the half-plane ABOVE the line because you want the y-values
to be GREATER than x+1.
{{{graph(400,300,-10,10,-10,10,y>x+1)}}}
============================================
2nd boundary 
y = 3
Graph that as a solid line because it is part of the solution:
Shade the half-plane ABOVE the line because you want ...GREATER than 3.
{{{graph(400,300,-10,10,-10,10,y > 3)}}}
=============
Note: The solution to the System is the intersection of the two solutions.
