Graphing inequalities with negative variables

WebNov 13, 2024 · Given a linear inequality in two variables, a x + b y < c, we use the steps below to graph a x + b y < c, where the the same process is applied for >, ≤, ≥ and a, b ≠ 0. Step 1. Rewrite the inequality in slope-intercept form, i.e., y = m x + b. Step 2. Graph the boundary line according to the two cases: Case 1. WebYou're always going to get or you should always get, the same slope. It's negative 1/2. So the equation of that line is y is equal to the slope, negative 1/2x, plus the y-intercept, minus 2. That's the equation of this line right …
