How to shade when graphing inequalities
WebUse a dashed line if < or > is used to indicate that the boundary is not part of the solution. Shade the appropriate region. Unless you are graphing a vertical line the sign of the inequality will let you know which half-plane to shade. If the symbol ≥ or > is used, shade above the line. If the symbol ≤ or < is used shade below the line.

WebExample 2: shade a region between two inequalities. Shade the region that satisfies the inequality -3\le y<1 −3 ≤ y < 1. Find a set of coordinates that satisfy a line given by the inequality. Show step. Join the points using a dashed line for \textbf {< / >} < / > or a solid line for \bf {\leq / \geq.} ≤ / ≥. Show step.
WebFollow these steps: Rearrange the equation so "y" is on the left and everything else on the right. Plot the " y= " line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>) Shade above the line for a "greater than" ( y> or y≥) or below the line for a "less than" ( y< or y≤ ). Now divide each part by 2 (a positive number, so again the inequalities don't chan… WebThe last step is to shade either above or below the boundary line. From the suggested steps, we were told to shade the top side of the boundary line if we have the inequality symbols > (greater than) or ≥ (greater than or equal to). Always remember that …
WebMar 7, 2024 · If the inequality shows you should shade in the area above the line. If the inequality shows , you should shade the area below the line. [7] For example, for the … WebApr 24, 2024 · To shade the two-variable inequality y<-2x + 3, first graph the line y=-2x + 3. Use a dashed line because the inequality is <, not ≤. Then test an x-y point on one side of the line. If the result makes sense, shade that side of the line. If not, shade the other. For instance, (3,4) gives 4<9, which checks out. Cite this Article
