Having trouble converting parametric equations to skew line equations! line 1- x=1+2r, y=1+2r, z= -3+r line 2- x=-2, y=s, z =2+s a.) Show that these lines are perpendicular to vector v= [1 -2 2]

Thankyou! but cross product for the vector of line 2 keeps equaling 4 and not 0?

Cross product? You mean dot product, don't you? You must have dropped the "-" from -2.
