3. Given the vector equation "-7" = (3, 1, 4> "l" 75(2, 21 5). Determine the points where this line intersects: the xy plane, the x2 plane, the yz plane, and the t value required in each case. Note, the line is in the xy plane when 2 = 0, etc. 4. Create a line through point P(9, 2, 3) and parallel to the line containing points A(4, 1, 1) and B( 3,6,0). Write both the vector and parametric forms of the line
