Answer 1

Ans: - 1

Three non - collinear can form only and only one plane.

if there are three points (x₁,y₁,z₁) , (x₂,y₂z₂) , (x₃,y₃,z₃) which forms a plane , then the equation of that plane will be

$\left|\begin{array}{ccc}x-x_1&y-y_1&z-z_1\\x_2 - x_1&y_2 -y&z_2-z_1\\x_3-x_1&y_3 - y_1&z_3 - z_1\end{array}\right| = 0 \\ \\ or \\ \\ \left|\begin{array}{cccc}x&y&z&1\\x_1&y_1&z_1&1\\x_2&y_2&z_3&1\\x_3&y_3&z_3&1 \end{array}\right| = 0$
