see explanation

Step-by-step explanation:

Given

2x + 3y = 4 ( subtract 2x from both sides )

3y = - 2x + 4 ( divide all terms by 3 )

y = - $\frac{2}{3}$ x + $\frac{4}{3}$

To determine if the point (2, 1) lies on the line, substitute x = 2 into the right side of the equation and if the value obtained equals the y- coordinate of the point then it lies on the line.

y = - $\frac{4}{3}$ + $\frac{4}{3}$ = 0 ≠ 1

Ths (2, 1) does not lie on the line
