The first step in determining the answer to this equation, is to substitute (0,0) into the equation.  

x=0 and y=0

So, 2x+6y+3>0

Becomes 2(0) +6(0) +3>0

              0 +0 +3>0

              3>0

3 is greater than 0; therefore, (0,0) is a correct solution for this equation.

Given

`2x+6y+3>0` ; (x,y)= (0,0)

to find whether (0,0) satisfies the inequality or not

sol:

By substituting (0,0) we will get to know whether it  satisfies the inequality.

`2x+6y+3>0` ;  (0,0)

=> 0+0+3>0

=> 3>0    : True

So , (0,0)  satisfies the inequality `2x+6y+3>0`
