How to shade when graphing inequalities
WebFeb 17, 2011 · Four worked-out examples demonstrating two techniques (primarily using logic) for determining where the shading goes, when graphing a linear inequality. WebMay 31, 2024 · A closed, or shaded, circle is used to represent the inequalities greater than or equal to ( ) or less than or equal to ( ). The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. The graph then extends endlessly in one direction.

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…

WebSep 10, 2024 · The method of graphing linear inequalities in two variables is as follows: Graph the boundary line (consider the inequality as an equation, that is, replace the inequality sign with an equal sign). ... Shade the half-plane on the opposite side of the boundary line. Example \(\PageIndex{4}\) Graph \(y > 2\). 1. Graph the boundary line \(y = … WebTo graph x ≥ -2, you have to know that ≥ is the greater than or equal to symbol. The equal part means you'll need to use a solid line on the boundary itself (x = -2). The greater than part means you'll need to shade the side of the line that has values of x that are more than-2.
WebWe will shade the bottom region of the boundary line because we have a “less than” case after we transformed the original inequality problem into the form in which the y is on the …
