y= -2/3x + 4
3x - 2y= 16
y= -2/3x + 4

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
slope of 2nd line = -2/3

neither?

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
