No, (2,2) is not solution of y < 4x - 6
Step-by-step explanation:
To solve above linear problem, we use standard method of  Back- Substitution. 
First of all, A point (2,2) only becomes solution of equation, if it satisfies equation  .
.
Here, the   seems to be like a linear equation.
  seems to be like a linear equation.
In this Equation, using  Back- Substitution method,
Point (2,2) : first digit 2 corresponds to x- coordinate and second digit 2 corresponds to y-coordinate.
            
By putting value of x and y in equation (1),
Equation becomes,
         
        
         .... not true mathematically.
      .... not true mathematically.
Finally, the result came is not true. Therefore, (2,2) is not solution for equation
