## anonymous 4 years ago Determine whether the lines through the pairs of points are parallel, perpendicular, or neither. 3x - 2y = -5 2x + 3y = -15 Choose one answer. a. parallel b. neither c. perpendicular

3x - 2y = -5 $\rightarrow y=(3/2)x +5/2$ 2x + 3y = -15 $\rightarrow y=(-2/3)x-5$ the gradients are $m_1={-1 \over m_2}$ which means they lines are perpendicular
