Given,
The equations of line are,
y = -1/6x + 2
y = 6x + 4
The standard form of equation of line is: y = mx+c
On comparing the equation of line to the standard equation then,
The slope of line is y = -1/6x + 2 is -1/6.
The slope of line is y = 6x + 2 is 6.
When the line are parallel then
[tex]m_1=m_2[/tex]When the line are perpendicular then,
[tex]m_1\times m_2=-1[/tex]Substituting the value of slopes then,
[tex]6\times\frac{-1}{6}=-1[/tex]Hence, the product of the slope of the line is equal to -1. So, the line are perpendicular to each other.
