The inequality from the givengraphis y≤-3x+5.What are inequalities?Inequalitiesare the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.From the graph, thecoordinatepoints are (2, -1) and (1, 2).Here, slope (m)=(2+1)/(1-2)m=-3Substitute m=-3 and (x, y)=(2, -1) in y=mx+c, we get-1=-3(2)+c-1=-6+cc=5Substitute m=-3 and c=5 in y=mx+c, we gety=-3x+5So, the inequality is y≤-3x+5Therefore, the inequality is y≤-3x+5.To learn more about theinequalitiesvisit:brainly.com/question/20383699.#SPJ7...
