In this multistep activity, you will review finding the determinant of a matrix. Then you will use this skill to find an equation for a plane given three points in the plane. . Step 1 (two-part question): Find the determinant of two matrices. . Step 2 (video): Given three points, finding an equation of the plane containing each. . Step 3 (equation entry question): Find an equation for a plane given three points in the plane. Find an equation of the plane passing through the points P = (0, 1, -1), Q = (8, 2, 8), and R = (47, 7, -9). Give your answer in the form 0 = ax + by + cz + d where a, b, c, de R. equation of the plane: -62x + 423y -47z - 532 =0 Incorrect
