Explanation The given linear inequalities are as follows, x + y ≤ 7 (1) x − y ≤ − 4 (2) 4 x + y ≥ 0 (3) Consider the equation (1). Since the inequality in the given equation is ≤ , the solid line is used to join the coordinates of this equation. Now, replace the inequality symbol in the given equation (1) with an “equals” sign. Then the equation (1) becomes, x + y = 7 . Obtain any 2 points of the above equation to plot on the line. Consider x = 0 , 7 and obtain the corresponding values of y respectively. Substitute x = 0 in the linear equation x + y = 7 . 0 + y = 7 y = 7 Thus, the value of y is 7 at x = 0 . Hence, the first coordinate is ( 0 , 7 ) . Substitute x = 7 in the linear equation x + y = 7 . 7 + y = 7 y = 7 − 7 y = 0 Thus, the value of y is 0 at x = 7 . Hence, the second coordinate is ( 7 , 0 ) . Therefore, the coordinates are ( 0 , 7 ) and ( 7 , 0 ) . Use the test point to determine the half plane which is to be shaded. Let the test point be ( 0 , 0 ) . Now substitute the test point ( 0 , 0 ) in x + y ≤ 7 . 0 + 0 ≤ 7 0 ≤ 7 It is noticed that the inequality x + y ≤ 7 is true. Thus, shade the half-plane that contains the test point ( 0 , 0 ) . Let us consider the equation (2). Since the inequality in the given equation is ≤ , the solid line is used to join the coordinates of this equation. Now, replace the inequality symbol in the given equation (2) with an “equals” sign. Then the equation (2) becomes, x − y = − 4 . Obtain any 2 coordinates from the above equation to plot on the line. Consider x = 0 , − 4 and obtain the corresponding values of y respectively. Substitute x = 0 in the linear equation x − y = − 4 . 0 − y = − 4 y = 4 Thus, the value of y is 4 at x = 0 . Hence, the first coordinate is ( 0 , 4 ) . Substitute x = 7 in the linear equation x − y = − 4 . − 4 − y = − 4 y = − 4 + 4 y = 0 Thus, the value of y is 0 at x = − 4 . Hence, the second coordinate is is ( − 4 , 0 ) . Therefore, the coordinates are ( 0 , 4 ) and ( − 4 , 0 )
