Question

determine whether each pair of lines is perpendicular parallel or neither. y - 4 = 3(x + 5), y + 3 = -1/3(x+1)

Answer 1

Explanation:

These are in the form
`y-y_1=m(x-x_1)` where
`m` is the gradient of the line.

So the gradients of the 2 lines are:
`3,-(1)/(3)`

Since
`3*-(1)/(3) =-1` the lines are perpendicular.

Answer 2

Yes they are.
