Graph: https://latex.artofproblemsolving.com/4/8/2/48234b947b623e95b3f920ee2e9ce6cb24dcfa4b.png
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 greater than 1
Thanks!!!!

The dotted line between the two regions means that this line is excluded from the solution region.

Two points which can be observed on the boundary line are (3,1) and (-3,-2).
This boundary line's equation:




------------just the boundary line equation.

If you want the yellow, upper region to be the solution then .
If you want the darkened, lower region to be the solution then .

The y-intercept of the boundary line is -0.5; the slope is 0.5. The equation of the boundary line in slope-intercept form is



The solution set is ABOVE the boundary line; the inequality is



The problem asks for the answer in ax+by+c>0 form:

.

The required inequality is


    y >        (1)


Tthe solution set is the set of all points (x,y) of the coordinate plane ABOVE the straight line 
(the domain shown YELLOW in the plot)


    y = .    (2)


The straight line itself is not included into the solution set.


Inequality (1) can be EQUIVALENTLY presented in the form


    2y - x + 1 > 0,            (3)


which has the required form.

Solved, answered, explained and completed.
