Question

which of the following would be neither perpendicular nor parallel to the following equation. y=3x-7. equations: y=-1/3x-7, y=-1/3x+5, y=1/3x+6, y=3x+1

Answer 1

y=1/3x+6

Explanation:

Equations parallel to each other have the same slope so that rules out the fourth answer. Perpendicular equations have opposite and reciprocal slopes, which in this case would be
`(-1)/(3)`, which rules out all of the others except for the third option.
