Question

Determine whether QR and ST are parallel, perpendicular, or neither Q(-1,4), R(-1, -9), S(11,-2),T(11,6)​

Answer 1

they are parallel!!!!!

Answer 2

I know I’m a little late, but these lines are parallel, not perpendicular, because they don’t intersect. The online calculator, desmos, is a great tool for checking these things!
