(C) Given that the point $(2, 3)$ lies on the graph of the equation $3x + ay = 18$.This means that the coordinates $x = 2$ and $y = 3$ must satisfy the given equation.Substituting $x = 2$ and $y = 3$ into the equation:$3(2) + a(3) = 18$$6 + 3a = 18$Subtracting $6$ from both sides:$3a = 18 - 6$$3a = 12$Dividing by $3$:$a = 4$.
