1. - A plane pass through the origin and has the direction vectors [6, — 7, 1] and [1, 1, 2]. Find a scalar equation of the plane. a) 6x c) 13x - 7y + z = 0 15y - 11z = 0 Work: b) x + y + 2z = 0 d) — 15x - 11y + 13z = 0 2. A line passes through the points A(-2,3) and B(-7,1). Find a vector equation of the line. . Work: a) [x, y] = [5,2] + t[− 2,3] c) [x, y] = [2,3] + t[− 7,1] - b) [x, y] = [ 7,1] + t[− 5, − 2] d) [x, y] = [5,2] + t[- 9,4]
