The slope of the line passing through points \( \left(x_{1}, y_{1}\right) \) and \( \left(x_{2}, y_{2}\right) \) is found using the formula \( \frac{y_{2}-y_{1}}{x_{2}-x_{1}} \),
The line passing through the points \( (1,2) \) and \( (x, 5) \) is perpendicular to a line that has a slope of \( \frac{1}{3} \). What is the value of \( x \) ?
(A) 10
(B) -2
