$$101$$

$$\eqalign{ & \mathop {\lim }\limits_{\left( {x,y} \right) \to \left( {2,9} \right)} 101 \cr & {\text{find the limit using }}\mathop {\lim }\limits_{\left( {x,y} \right) \to \left( {a,b} \right)} k = k,{\text{ k is a constant}} \cr & {\text{for this exercise }}k = 101 \cr & {\text{then}} \cr & \mathop {\lim }\limits_{\left( {x,y} \right) \to \left( {2,9} \right)} 101 = 101 \cr} $$
