The graph of the inequality 2x+3y>6 is
Solution:
Given inequality 2x+3y>6
3y>6−2x
y>6−2x3
Now consider y=6−2x3 and plot the graph [Ref. image ]
X O 3
Y 2 O
we used dashed as
y>6−2x3 as there in no equal to sign
∵y is greater than 6−2x3 we will shade the upper part [Ref. image 2]
Thus the graph of 2x+3y>6 is drawn
