Correct Answer - Option 3 : y – 4x + 13 = 0
Concept used:
The general equation of a line is y = mx + c
where m is the slope and c is any constant
- Slope of parallel lines are equal.
- Slope of perpendicular line have their product = –1
Equation of a line with slope m and passing through (x1, y1)
(y – y1) = m (x – x1)
Calculation:
Given the line has the slope 3 and passes through (4, 3)
∴ Equation of the line is
(y – y1) = m(x – x1)
⇒ y – 3 = 4 (x – 4)
⇒ y – 4x + 13 = 0
