\\We know that at x-axis y = 0\\ Hence we have to find distance of P(2, 3) from Q(2, 0)\\ (x\textsubscript{1}, y\textsubscript{1}) = (2,3) (x\textsubscript{2}, y\textsubscript{2}) = (2,0)\\ Let the distance between them is PQ\\ Distance formula = \sqrt{{{({{x}_{2}}-{{x}_{1}})}^{2}}+{{({{y}_{2}}-{{y}_{1}})}^{2}}} \\ PQ=\sqrt{{{(2-2)}^{2}}+{{(0-3)}^{2}}} \\ PQ=\sqrt{0+9}=\sqrt{9}=3 \\ PQ = 3\\
