If lines 3x - y =2,5x + ay = 3 and 2x + y = 3 are concurrent ,then a =
2
3
-1
-2
The equation of sides of a quadrilateral AB,BC,CD, and DA are x + 2y = 3, x = 1, x - 3y = 4,5x + y + 12 = 0, the angle between diagonals AC and AD is
The angle between lines and is.
The equation of line joining origin to (-4,5) is
5x + 4y = 0
5x - 4y = 0
4x + 5y = 0
4x - 5y = 0
Lines x + y - 4 = 0 , 3x + y - 4 = 0 and x + 3y - 4 = 0 and x + 3y - 4 = 0 form a triangle which is
An isosceles
A right angle
An equilateral
None of these
A straight line makes angle 135o with x - axis and cut y - axis at distance -5 from origin.The equation of line is
2x + y + 5 = 0
x + 2y + 3 = 0
x + y + 5 = 0
x + y + z = 0
The equation of two lines which pass through the point (3,2) and make angle of 45o with the line x - 2y = 3 are
3x + y + 7 = 0 and x + 3y + 9 = 0
3x - y - 7 = 0 and x + 3y - 9 = 0
x + 3y - 7 = 0 and x + 3y - 9 = 0
The equation of a line passing through (3,-4) and perpendicular to line 3x + 4y = 5 is
4x + 3y = 24
y - x = x + 3
3y - 4x = 24
y + 4 = 4/3 (x - 3)
Line L is perpendicular to line 5x - y = 1.The area of triangle formed by coordinates axis and line is 5 sq . units.Then its equation is
x + y = √2
x + 5y = ± 5 √2
x + 5y = -5
x + 5y = - √2
The equation of a line passing through the intersection point of lines x - 2y = 1 and x + 3y = 2 and parallel to lines 3x + 4y = 0 is.
3x + 4y + 5 = 0
3x + 4y - 10 = 0
3x + 4y - 5 = 0
3x + 4y + 6 = 0
