What will be the equation of line which passes through the point (–2, 3) and parallel to any other line 3x – 4y + 2 = 0
-
- 3 x – 4y + 18 = 0
- –3x + 4y + 12 = 0
- x – 3y + 10 = 0
- 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 = | |
- 4 |
[From equation 3x – 4y + 2 = 0]
m2 = | |
4 |
As lines are parallel.
∴ m1 = m2
⇒ m = | |
4 |
Let the equation of line be y – y1 = m(x – x1)
As line passes through (–2, 3)
∴ Equation of line be
(y - 3) = | (x + 2) | |
4 |
4y – 12 = 3x + 6
3x – 4y + 18 = 0
