(3*5-11)+(3*13-15)+(1*11-9)= 30
(15-11) + (39-15) + (11-9 ) = 30
4+24+2= 30
30 = 30
So, in this only the numbers given above is used , no gaps are left and I didn't even use 0.
So, i guess my answer is right.
Given the following equations
The graphical representation of all the above equations is as shown below:
From the above graphical representation, it can be observed that the second equation matches the given graph
Hence, the equation that matches the given graph is 6x+y = 6
