Text Solution

AI Generated Solution

To find the equation of a line passing through the points (3, 5) and (-2, 1), we can use the determinant method. The general form of the equation of a line passing through two points \((x_1, y_1)\) and \((x_2, y_2)\) can be expressed using a determinant as follows: \[ \begin{vmatrix} x & y & 1 \\ x_1 & y_1 & 1 \\ x_2 & y_2 & 1 \end{vmatrix} = 0 ...
