Question

Determine whether the pair of lines is parallel, perpendicular, or neither. Y=-6/5x+2 Y=6/5x+2

Answer 1

`k:y=m_1x+b_1;\ l:y=m_2x+b_2\\\\k\ \perp\ l\iff m_1\cdot m_2=-1\\\\k\ ||\ l\iff m_1=m_2`

`k:y=-(6)/(5)x+2\to m_1=-(6)/(5)\\\\l:y=(6)/(5)x+2\to m_2=(6)/(5)\\\\m_1\\eq m_2\to\text{no parallel}\\\\m_1\cdot m_2=-(6)/(5)\cdot(6)/(5)\\eq-1\to\text{ no perpendicular}`

Answer: NEITHER
