Q) Find the ratio in which line y = x divides the line segment joining the points (6, -3) and (1, 6). Ans: Let’s draw the diagram to solve: Also consider that the line y = x divided the line PQ in the ratio of m : n. By section formula, if a point (x,
Q) Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is.The left-right (horizontal) direction is commonly called X-axis.The up-down (vertical) direction is commonly called Y-axis.In Green Park, New Delhi Suresh is having a rectangular plot ABCD as shown in the following figure. Sapling of Gulmohar

Her father felt that the game can be better understood if the position of players
Q) Find the ratio in which y-axis divides the line segment joining the points (5, – 6) and (- 1, – 4). Ans: Let’s draw the diagram to solve: Let’s consider the coordinates of point P is (0,y) Also consider that the line AB is divided in ratio of m : n. By section formula,
Q) Point P(x, y) is equidistant from points A(5, 1) and B(1,5). Prove that x = y. Ans: Let’s draw the diagram to solve: Given that PA = PB Hence, PA2 = PB2 (x – 5)2 + (y – 1)2 = (x – 1)2 + (y – 5)2 – 10 x – 2y = –
Point P(x, y) is equidistant from points A(5, 1) and B(1, 5). Prove that x = y. Read More »
Q) The line segment joining the points A(4,-5) and B(4,5) is divided by the point P such that AP : AB = 2 : 5. Find the coordinates of P. Ans: Let’s draw the diagram to solve: Given that (AB = AP + PB) by cross multiplication, we get: 5 AP = 2 (AP
Q) Jagdish has a field which is in the shape of a right angled triangle AQC. He wants to leave a space in the form of a square PQRS inside the field for growing wheat and the remaining for growing vegetables (as shown in the figure). In the field, there is a pole marked as
