There are several ways to find a equation of a line that satifies some conditions.
I'll go with the least theory heavy.
A line can be represented as $$y=mx+b$$
Where "m" represents the slope and "b" the y-interception. Another tool you might want to use is the condition of perpendicularity:
$$m_1 m_2 = -1$$
or if you prefer:
$$m_1 = -\frac{ 1 }{ m_2 }$$
This just means, that in order for a slope "1" to be perpendicular to a seconde slope "2", it has to be reciprocal and opoosite to the slope "1".
