Hi could you please answer question 10 and 11 clearly thank you

10. The equation of a plane is [x, y, z] = [- 1, 0, 0] + s[- 1, 0, 1] + t[- 1, 2, 0]. Find vector YZ, where Y is the y - intercept of the plane and Z is the z intercept. [3 marks] 11. Determine the distance between the point (- 1, 2, 1) and the plane 2x + 14y - 5z = 7 [3 marks]
