perpendicular

Answer 1

Neither parallel nor perpendicular

Explanation:

The lines represented by the equations y = 1x – 5 and 3y + x = -15 are .....

Solve for y in 3y + x = -15.

`3y + x = -15 \\ ( - x = - x)/(3y = - x - 15) \\ \\ (3y = - x - 15)/(3 \: \: = \: \: \: \: \: \: \: \: \: 3) \\ y = - (1)/(3)x - 5`

`y = - (1)/(3)x - 5 \: and \: y = 1x - 5`
