given equation,
-3x + 2y ≥ -6
for solving , follow the below steps :
step1:- consider the equation as strict equation.
e.g. -3x + 2y = -6
step2:- find the points on the x-axis and y-axis.
e.g. when x = 0 , y = -3
when y = 0 , x = 2
step3:- plot the graph of -3x + 2y = 6 by using above data 's .
step4:- take a point ( 0,0) and put it in given inequation (1) we get ,
0 + 0 ≥ -6 which is true . hence, shaded region will be towards the origin (0,0)
thus, shaded region shows inequality.
