State whether the two lines in each of the following are parallel, perpendicular or neither: through (6,3) and (1,1); through (-2,5) and (2,-5)

Explanation

Slope of line joining `(6,3) `and `(1,1)`


`m_{1}=frac{1-3}{1-6}=frac{-2}{-5}=frac{2}{5}`


Slope of line joining `(-2,5)` and `(2,-5)`


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