Given the points A(-1, 2), B(1, -1) and C(2, 1). 22. Find the equation of the parabola passing through these points and having its axis horizontal. a. 6y2 + 5x - 3y - 13 = 0 c. 7y2 + 6x - 3y - 16 = 0 b. 6y2 + 3x - 3y - 15 = 0 d. 7y2 + 4x - 3y - 18 = 0 23. Find the parabola through these points with axis vertical. a. 6x2 - 9x - 6y - 3 = 0 c. 6x2 - 7x - 6y - 1 = 0 b. 7x2 - 9x - 6y - 4 = 0 d. 7x2 - 7x - 6y - 2 = 0
