hi please help i'm not understanding thank you so much

x =s+t 5. The parametric equations of a plane m: y = 1 + t. Find a scalar equation of the plane. =1-s a) x- y+z-2=0 b ) xty+z=0 c) x - y+z =0 d) x-y+z+2=0 6. Find the intersection point of the two lines: 11: ) _ 2, and 12: * = 1+ s = -1+s a) (5,4) b) (1, - 1 ) c) (4,2) d) (1, 1) 7. In three-space, find the intersection point of the two lines: [x, y, z] = [3, 4, 0] + 1 [1, 1, 2] and [x, y, z] = [-1, 4, -20] + s [0, -1, 3]: a) (-1,0, -8) b ) (2, 0, - 3 ) c) (-4, -5,-8) d) (-4, -5, 1) x = 1+ 2t x = 2+3s 8. In three-space, find the intersection point of the two lines: y = -3 + t & y = -1 + 2s z = -3 Z = S a) (1, -3, -3) b) (2, 1, -3) c) (2, -1,0) d) (-7,-7,-3) 9. By analyzing the normals, determine if the two planes: m: x+ 2y+ 32 - 3=0 & 12: 2x - y+z- 7=0 a) intersect in a line b) are parallel and distinct C) are coincident d) intersect at a point 10. By analyzing the normals, determine if the three planes: m: x+ 2y+ 32 - 4 =0 & 12: 2x + 4y + 6z + 8 = 0 & 13: 4x + 8y + 12z - 10 = 0 a) intersect in a line b) are parallel and distinct c) are coincident d) intersect at a point
