cartesian equation of the given line is \(\frac{x-3}{1}\) = \(\frac{y-1}{2}\) =\(\frac{z+1}{-2}\)
Hence its direction ratios are‹1, 2, –2›
The cartesian equation of the line is given by
\(\frac{x-x_1}{b_1}=\frac{y-y_1}{b_2}=\frac{z-z_1}{b_3}\) the point is (1, –1, 2) and the direction ratios are ‹1, 2, –2›
The cartesian equation of the line is
Let this be equal to \(\lambda\)
Hence comparing 1 & 2
The vector equation of the line is given as
