Q75
What is the equation of the line perpendicular to the line 2x + 3y = -6 and having Y-intercept 3?
A.
3x - 2y = 6
B.
3x - 2y = -6
AnswerC.
2x - 3y = 6
D.
2x - 3y = -6
Answer: Option B
Solution
Answer: Option B
Solution:
⇒ Two lines are perpendicular if m1 × m2 = -1
Y intercept = 3
⇒ y = mx + c
⇒ m2 =
The equation of line with slope is:-
y - y1 = m2(x - x1)
where, (x1 y1) = (0, 3)
y - 3 = (x - 0)
2y - 6 = 3x
3x - 2y = -6
