Question

The line parallel to Y-axis and passing through the point ($-$3,5).

Answer 1

The equation of the line parallel to the y-axis (i.e., slope, m = $\frac{1}{0}$) and passing through the point ($-$ 3, 5) is
y $-$ y₁ = m (x $-$ x₁)
⇒ y $-$ 5 = $\frac{1}{0}${x $-$ ($-$3)}
⇒ x + 3 = 0
⇒ x = $-$3
