Find the values of k for which the line (k–3) x – (4 – k2) y + k2 – 7k + 6 = 0 is passing through the origin.
Show Answer
What are the points on the y-axis whose distance from the line x + 3y = 4 is 4 units?
Show Answer
Find the equation of the line parallel to the y-axis and passing through the point of intersection of the lines x – 7y + 5 = 0 and 3x + y = 0.
Show Answer
Find the distance of the line 4x + 7y + 5 = 0 from the point (1, 2) along the line 2x – y = 0.
Show Answer
Find the direction in which a straight line must be drawn through the point (-1, 2) so that its point of intersection with the line x + y = 4 may be at a distance of 3 units from this point.
