First, you must know how to solve linear inequalities with symbols <, >, ≤ , ≥ .
Find the x- and y-intercepts of the given equation, and plot them.
a.) To find the x-intercept, omit y in the equation then solve for x. The x-intercept is at (x,0).
b.) To find the y-intercept, omit x in the equation then solve for y. The y-intercept is at (0,y).
If the symbol of inequality is < or >, connect the intercepts with broken lines.
If the symbol of inequality is ≤ or ≥, connect the intercepts with solid lines.
If there are two equations in the system with the same variables, the same procedure applies for each equation.
