Question

determine if the lines 9x - 2y = 16 and 2x - 9y = -18 are parallel, perpendicular, or neither? parallel correct?

Answer 1

how did you come to that conclusion?

Answer 2

neither

Answer 3

for function 1: \[9x-2y=16\]\[y=(9/2)x-8\]
for function 2: \[2x-9y=-18\]\[y=(2/9)x+2\]

The slopes are not the same, nor or they negative reciprocals, so they are neither.
