Graphing inequalities with negative variables
WebSep 27, 2024 · To graph an inequality: Graph the related boundary line. Replace the <, >, ≤ or ≥ sign in the inequality with = to find the equation of the boundary line. Identify at least one ordered pair on either side of the … WebExample 1: Graph the linear inequality y>2x-1 y > 2x − 1. The first thing is to make sure that variable y y is by itself on the left side of the inequality symbol, which is the case in this problem. Next is to graph the boundary …

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 … WebWhen solving inequalities, like, say, this one: -2x+5<25. You would cancel out the +5 with -5 and subtract 25 by 5, so you're left with this: -2x<20. But now, since you're dividing by -2 (remember that multiplying or dividing by a negative number will reverse the sign) it will no longer be less than, it will be greater than: -2x/-2>20/-2.
WebMar 7, 2024 · Multiplying or dividing the same NEGATIVE number to both sides of an inequality reverses the sign of the inequality. If a < b and c is negative, then ac > bc If … WebStep 1: We need to rewrite the inequality so that it is in slope intercept form. Step 2: Graph the line. Note that the line is solid because the inequality sign is greater than or equal to. Step 3: Shade the solution set. Since y is greater than the expression, shade the side "above" the line.
WebGraph the inequality on a number line by drawing a circle over the number. Fill it if the inequality has a ≥ or ≤, leave it unfilled if it has a > or <. Draw a line toward the right, if the solutions are greater than the number and … WebIf both sides of an inequality are multiplied or divided by the same positive quantity, the inequality remains true. If we multiply or divide both sides of an inequality by the same …
WebVideo transcript. Graph the inequality y minus 4x is less than negative 3. So the first thing we could do is we could kind of put this in mx plus b form, or slope-intercept form, but as an inequality. So we're starting with y …
