The equation of line parallel to the y-axis is x = -5/22
How to determine the equation of the parallel line
From the question, we have the following parameters that can be used in our computation:
x − 7y + 5 = 0
3x + y = 0
Make y the subject of the formula in (2)
So, we have
3x + y = 0
y = -3x
Substitute y = -3x into the equation x − 7y + 5 = 0
So, we have
x - 7 * -3x + 5 = 0
x + 21x + 5 = 0
Evaluate the like terms
22x + 5 = 0
22x = -5
Divide both sides by 22
x = -5/22
Hence, the equation of the parallel line is x = -5/22
