MCQ

Find the equation of line parallel to y-axis and passing through (3, 4):

✓
x = 3
B
x = 4
C
y = 4
D
y = 3

✓

Answer

Correct option: A.

x = 3

x = 3

Solution:
Let general equation of line be y = m (x - d)
$\Rightarrow\text{x} = \frac{\text{y}}{\text{m + d}}$
Since line is parallel to y-axis so, $\text{m}=\frac{1}{0}$ or $\frac{1}{\text{m}} =0$
⇒ x = d
⇒ x = 3 by substituting the point (3, 4).
