Are the below pairs of lines parallel, perpendicular, or neither?

9x+12y = 8 and 6x+8y = - 1

Parallel

Perpendicular

Neither

9x + 12y = 8

12y = - 9x + 8

y = - 3/4x + 2/3 ... slope here is - 3/4, y int is 2/3

6x + 8y = - 1

8y = - 6x - 1

y = - 3/4x - 1/8 ... slope here is - 3/4, y int is - 1/8

same slope, different y intercepts means parallel lines

They are parallel to eachother
