how can i solve this question ?

Please give me full explanation

Another approach to nding the line of intersection of the two planes x+6y+z=4 0 4 0 x: 1 +1 2 +y 3 0 0 4 and is to rst convert both into Cartesian form, and then solve the system of two equations. Since a normal vector to the second equation is n = g :1 and the oo-ordinate vector for a point on the plane is p = we can write the second plane in point-normal form: (x p)- n = 0. Note: the Maple syntax for a vector is . This becomes the Cartesian equation I:II- Note: the maple syntax for the Cartesian equation x + 6 y + z = 4 is x + 6 * y + z = 4. 1 6 1 Reducing the system of two linear Cartesian equations to row-echelon form leads us to the augmented matrix (A lb) whereA = ( 1 ) and b = 0 8 :El Note: enter 1) as a two dimensional vector, e.g. . From this we can determine that the intersection of the two planes is a line which is parallel to the vector :] E; j and where :] is the co-ordinate vector for a point on the line. Note: use the Maple syntax for a vector for both these answers, e.g.
