To the lines ax2 + 2hxy + by2 = 0, the lines a2x2 + 2h(a + b) xy + b2y2 = 0 are
equally inclined
perpendicular
bisector of the angle
None of these
If R be a realtion from A = {1, 2, 3, 4} to B = {1, 3, 5} such that (a, b) ∈R , then ROR-1 is
{(1, 3), (1, 5), (2, 3), (2, 5), (3, 5), (4, 5)}
{(3, 1), (5, 1), (3, 2), (5, 2), (5, 3), (5, 4)}
{(3, 3), (3, 5), (5, 3), (5, 5)}
{(3, 3), (3, 4), (4, 5)}
A line passes through (2, 2) and is perpendicular to the line 3x + y = 3. What is its y intercept
1/3
2/3
1
4/3
D.
4/3
Equation of the line perpendicular to 3x + y - 3 = 0 is
x - 3y + c = 0
Since it passes through (2, 2).
c = 4
Equation of line perpendicular to 3x + y - 3 = 0 is x - 3y + 4 = 0
For y - intercept, put x = 0
