Question

Select the linear inequality in two variables that is represented by the shaded region.- y>= 3x + 1 - y< 3x + 1 - y<= 3x + 1 - y > 3x + 1

Answer 1

Given: a graph of inequality is given

Find: the equation

Explanation: from the graph we will right the equation of the line ,and shaded area is greater than type , so the equation becomes

$\begin{gathered} \frac{x}{\frac{-1}{3}}+\frac{y}{1}\ge1 \\ -3x+y\ge1 \\ y\ge3x+1 \end{gathered}$
