The equation \(\overline r\) = \(\overline a\) + s\(\overline b\) + t\(\overline c\) represents a plane passing through a point having position vector \(\overline a\) and parallel to the vectors \(\overline b\) and \(\overline c\) .
Here, \(\overline a\) = \(\hat i+\hat j\), \(\overline b\) (\(\hat i+\hat j\) +\(2\hat k\)) and \(\overline c\) (\(\hat i+2\hat j\) +\(\hat k\))
The given plane is perpendicular to the vector \(\overline n\)
