Find a linear inequality with the following solution set. Each grid line represents one unit. 

(Give your answer in the form \(ax+by+c>0\) or \(ax+by+c\geq0\) where \(a, b\) and \(c\) are integers with no common factor other than 1.)

 

Hint(s):

First, find the equation of the red line.

The line equation is   y = 2x - 4     everything in yellow is less than this  (but includes the line)  

           y <= 2x-4

 

         2x-y-4 >=0

But a and b have a common factor of 2, which doenst go with "integers with no common factor other than 1"

it says   'a'  'b' and 'c' have no common factors other than one     NOT    'a' and 'b' have no common factors other than one
