Explanation Given: The given set of inequality is { x + y > 4 x + y > − 1 Graph: Consider, the provided inequalities { x + y > 4 x + y > − 1 . Rewrite the corresponding equations by substituting “equal to” symbol in the place of inequality symbols as shown below: x + y = 4 x + y = − 1 First, consider equation x + y = 4 and put y = 0 in the equation to compute the value of x -intercept as shown below: x + y = 4 x + 0 = 4 x = 4 Thus, the point through which line passes is ( 4 , 0 ) . Now, put x = 0 in the equation to find the value of y -intercept as shown below: x + y = 4 0 + y = 4 y = 4 Thus, the obtained coordinates of the line is ( 0 , 4 ) . Consider the second equation x + y = − 1 and put y = 0 in the equation to compute the value of x -intercept as shown below: x + y = − 1 x + 0 = − 1 x = − 1 Thus, the obtained coordinates are ( − 1 , 0 )
