Given equation of lines are
x – 7y + 5 = 0 ... (i)
and 3x + y = 0 ... (ii)
On solving (i) and (ii), we get
x =

−5

22

, y =

15

22

∴ The point of intersection of the given lines is (−

5

22

,

15

22

)
Thus equation of the line parallel to y-axis and drawn through the point (−

5

22

,

15

22

) is x = −

5

22

which can be re-written as 22x + 5 = 0.
