Steps to Graphing a Linear Inequality • Verify the inequality is in slope-intercept form (the equal sign is replaced with an inequality symbol) • Plot the y-intercept • Graph additional points using the slope • Draw a line through the plotted points • Solid line - • Dashed line -
Steps to Graphing a Linear Inequality • Select two points – one from each side of the line • Substitute the points into the originalinequality, check for truth value • Shade the region containing the point that made the inequality statement true
