Tell if the following pair of lines is parallel, perpendicular, or neither.

3x - 2y= 16
y= -2/3x + 4
Answered by Reiny
slope of first line = 3/2
slope of 2nd line = -2/3

draw your conclusion based on what you must have learned about lines and their slopes

neither?
Answered by Reiny
no, they are perpendicular

I one line has a slope of a/b then a perpendicular line has slope of -b/a , that is,
one slope is the opposite reciprocal of the other.

That is the case here: 3/2 vs -2/3
