Is y=3x+8 perpendicular, parallel, or neither?

The answer to the question is Parallel

In 3x - y = - 1

-y = - 3x - 1 {subtracted 3x from both sides to get into slope-intercept form}

y = 3x + 1 {divided both sides by - 1}

the slope is 3 {the number in front of the x}

The slopes are the same in both equations, therefore

the lines are parallel.
