4x%2B4y%3C20+...simplify, divide by 4
x%2By%3C5+
find two point, x%2By=5+
make table:
0|y..y=5+
5|0..y=5+
the line of x%2By=5+ should be dashed because its points are not part of solution for x%2By%3C5+

Graph 4x+4y<20 in a coordinate plane and sketch the boundary line of the graph.
------------
Graph 4x+4y=20 --> x+y = 5
-----
It's a straight line, you need 2 points.
x+y < 5 is the area below and to the left of the line, the line not included.
