Find equation of a line that is perpendicular to another line
lawyer [7]
Let ax+by=c be the given(known) line 
slope of this line (m₁) = -a/b 

Let m₂ be the slope of required line
Since given line and required line are perpendicular to each other, the product of their slopes must be equal to -1
Therefore, m₁.m₂ = -1
(-a/b)m₂ = -1
m₂ = b/a

Therefore, by slope-intercept form, line perpendicular to given line can be given by,

y=m₂x+c
y=(b/a)x+c
Therefore, ay-bx=c 
or bx-ay+c = 0
Where c is constant and it can be determined according to the conditions given in questions.
Therefore the required line is,

bx-ay+c=0

The answer is 2/7 or 0.28571428... You can find this the same way as your other problem by finding the common denominator and multiplying. (Also, if you go on Mathway, you can find solutions to almost any problem really quickly.)
Hope this helps!
