State whether the tow lines in each of the following are parallel, perpendicular or nether: through (9,5) and (-1,1); through (3,-5) and (8,-3)

Explanation

Slope of line joining `(-1,1) `and `(9,5)`

`m_{1}=frac{5-1}{9-(-1)}=frac{4}{10}=frac{2}{5}`

Slope of line joining` (3,-5) `and `(8,-3)`


`m_{2}=frac{-3-(-5)}{8-3}=frac{-3+5}{5}=frac{2}{5}`


Here `m_{1}=m_{2}`
Therefore,
