NO

Explanation:

We have, #7x+9y=color(red)(2)#
For (6,4), we take #x=6 and y=4# in LHS.
So, #LHS=7(6)+9(4)=42+36=78!=color(red)(2)#
Hence, #LHS!=RHSrArr(6,4)#, is not a solution of 7x+9y=2

If a given plane point is solution of a linear equation, then it verifies the equation#. Lets see

Explanation:

#(6,4)# are the coordinates of a plane point where the first is the value of x, and the second one is the value of y.

#7·6+9·4=42+36=78!=2#. Then, the given point is not a solution of #7x+9y=2#
