  1. What will be the equation of line which passes through the point (–2, 3) and parallel to any other line 3x – 4y + 2 = 0
    1. 3 x – 4y + 18 = 0
    2. –3x + 4y + 12 = 0
    3. x – 3y + 10 = 0
    4. 2 x + 3y + 6 = 0
Correct Option: A

When two lines are parallel then their slopes are equal. i.e. m1 = m2
Here,
m1 = m

m1 =
- 3
- 4

[From equation 3x – 4y + 2 = 0]
m2 =
3
4

As lines are parallel.
∴ m1 = m2
⇒ m =
3
4

Let the equation of line be y – y1 = m(x – x1)
As line passes through (–2, 3)
∴ Equation of line be
(y - 3) =
3
(x + 2)
4

4y – 12 = 3x + 6
3x – 4y + 18 = 0
