Because of the strict inequality, we will graph the boundary y = − 3 x 1 using a dashed line We can see that the slope is m = − 3 = − 3 1 = r i s e r u n and the y intercept is (0, 1) Step 2 Test a point that is not on the boundaryIf substituting (x, y) into the inequality yields a true statement, then the ordered pair is a solution to the inequality, and the point will be plotted within the shaded region or the point will be part of a solid boundary lineA false statement means that the ordered pair is not a solution, and the point will graph outside the shaded region, or the point will be part of a dotted boundary lineNow an inequality uses a greater than, less than symbol, and all that we have to do to graph an inequality is find the the number, '3' in this case and color in everything above or below it Just remember if the symbol is (≥ or ≤) then you fill in the dot, like the top two examples in the graph below if the symbol is (> or
