GRAPHICAL SOLUTION OF INEQUALITIES IN TWO VARIABLES

A straight line has the general equation ax+by+c=0, where a,b and c are real numbers.

 

The line ax + by + c =0 partitions the x-y plane into two regions

Worked Examples

1)   Show the region representing 2x + y + 1 > 0

    Solution

2x + y + 1 > 0

Steps

  1.  make y.... View More
