Question

Find the equation of a line parallel to $$y$$-axis and passing through the point (–7, 5).

Answer 1

The equation of any line parallel to the $$y$$-axis is of the form: $$x = a$$. 

Since the line passes through $$(-7, 5)$$, its $$x$$-coordinate is $$-7$$. 

Therefore, the required equation is $$x = -7$$ or $$x + 7 = 0$$.
