If a line passes through two points (1, 5) and (3, 7) find its equation.
x – y + 4 = 0
i.e., y – 5 = x – 1
i.e., x – y + 4 = 0
If a2 + b2 – c2 – 2ab = 0 then the point of concurrency of family of straight lines ax + by + c = 0lies on the line –
All chords of the curve 3x2 – y2 –2x + 4y = 0 that subtends a right angle at the origin, pass through a fixed point whose co-ordinate is –
In a triangle ABC, and point A lies on line y = 2x + 3 where Area of is such that [âˆ†] = 5. Possible co-ordinates of âˆ† is/are –
then the point (x, y) lies on same side of the line 2x + y – 6 = 0 as the point –
Find the area of the quadrilateral with vertices (3, 3), (1, 4), (–2, 1), (2, –3).
A straight line segment of length ‘p’ moves with its ends on two mutually perpendicular lines. find the locus of the point which divides the line in the ratio 1:2.
Find the acute angle between the two lines with slopes 1/5 and 3/2.
If a line has a slope = ½ and passes through (–1, 2); find its equation.
If a line has a slope 1/2 and cuts off along the positive y-axis of length 5/2 find the equation of the line.
A straight line passes through a point A (1, 2) and makes an angle 60owith the x-axis. This line intersects the line x + y = 6 at the point P. find AP.
