Please solve them asap with good handwriting Thank you.It's a grade 12 calculus class.

1) Find a vector equation for the line x=5-2t, y=-t, z=t-7 2) Find parametric and symmetric equations of the line through the points P(5,3,-1) and Q(3,1,-6). Parametric: Symmetric: - 3) Show relevant work to determine whether the equations given represent the same line. L1: (x,y)= (2,2) + s(4,-2) L2: (x,y) = (18,-6) + +(-8,4)
