The graph of the inequality 2x+3y>6 is
Given inequality 2x+3y>6
3y>6−2x
y>‌
6−2x
3

Now consider y=‌
6−2x
3
and plot the graph [Ref. image ]
X O 3
Y 2 O
we used dashed as
y>‌
6−2x
3
as there in no equal to sign
∵y is greater than ‌
6−2x
3
we will shade the upper part [Ref. image 2]
Thus the graph of 2x+3y>6 is drawn
Among the option only {B} true
