Q. Write the following inequality in slope-intercept form. −7x−y≥21 Write your answer with y first, followed by an inequality symbol. Use integers, proper fractions, and improper fractions in simplest form.
Identify Equation Form: Identify the slope-intercept form of an equation.The slope-intercept form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.
Isolate y in Inequality: Isolate y in the inequality −7x−y≥21. To isolate y, we need to add y to both sides of the inequality and subtract 21 from both sides. −7x−y+y≥21+y−7x≥y+21 Now, subtract 21 from both sides to get y by itself. −7x−21≥y
Rewrite Inequality: Rewrite the inequality with y on the left side.To match the slope-intercept form, we need y to be on the left side of the inequality. Since the inequality is currently y≤−7x−21, we can multiply both sides by −1 to reverse the inequality sign and get y on the left.y≤7x+21However, when we multiply or divide both sides of an inequality by a negative number, we must reverse the inequality sign.y≥−7x−21
