Straight Line (Part 2/3) JEE Main PYQ + Theory | Prabhat Ranjan

Straight Line Question 11-20 (Part 2/3) Class 11, 12 Mathematics Boards, JEE Main, JEE Advanced, IIT JEE Full course from basic JEE Main Question Practice JEE Main PYQ + Theory by Prabhat Ranjan for class 12, boards, IIT JEE 2025, JEE Main 2025, JEE Advanced 2025, IIT JEE 2026, JEE Main 2026, JEE Advanced 2026.

"Straight Line (Part 2/3) JEE Main PYQ + Theory" by Prabhat Ranjan covers questions 11-20, continuing the exploration of straight lines for Class 11, 12, and JEE aspirants. This part delves deeper into key straight-line concepts, such as the angle between two lines, conditions for perpendicularity and parallelism, and the distance of a point from a line. The session also includes JEE Main-specific previous year questions (PYQs), ensuring students get a practical understanding of how the topic is tested in competitive exams like IIT JEE 2025 and 2026.

All these aspects have been covered by Prabhat Ranjan in full detail in his new YouTube video.

Timeline:
00:00 Introduction
01:49 11) If the perpendicular bisector of the line segment joining the points P(1, 4) and Q(k, 3) has y-intercept equal to -4, then a value of k is
08:18 12) A ray of light coming from the point (2,2 root3) is incident at an angle 30° on the line x = 1 at the point A. The ray gets reflected on the line x = 1 and meets x-axis at the point B. Then, the line AB passes through the point
22:32 13) Let L denote the line in the xy-plane with x and y intercepts as 3 and 1 respectively. Then the image of the point (-1, -4) in this line is
31:10 14) If the curve x2 + 2y2 = 2 intersects the line x + y = 1 at two points P and Q, then the angle subtended by the line segment PQ at the origin is
42:07 15) The intersection of three lines x - y = 0, x + 2y = 3 and 2x + y = 6 is a [JEE-MAIN_26-02-2021_S1] (1) Right angled triangle (2) Equilateral triangle (3) Isosceles triangle (4) None of the above
48:19 16) The number of integral values of m so that the abscissa of point of intersection of lines 3x + 4y = 9 and y = mx + 1 is also an integer, is
55:51 17) The equation of one of the straight lines which passes through the point (1, 3) and makes an angles tan-1 root 2 with the straight line y +1=3/2x is
01:06:45 18) Let the equation of the pair of lines, y = px and y = qx, can be written as (y - px) (y - qx) = 0. Then the equation of the pair of the angle bisectors of the lines x2 - 4xy - 5y2 = 0 is
01:12:01 19) The point P (a,b) undergoes the following three transformations successively : (a) reflection about the line y = x. (b) translation through 2 units along the positive direction of x-axis. (c) rotation through angle pi/4 about the origin in the anti-clockwise direction. (d) If the co-ordinates of the final position of the point P are (-1/7 root 2, -7/ root 2),
then the value of 2a + b is equal to
01:18:00 20) Two sides of a parallelogram are along the lines 4x + 5y = 0 and 7x + 2y = 0. If the equation of one of the diagonals of the parallelogram is 11x + 7y = 9, then other diagonal passes through the point
