CHAPTER-15, COORDINATE GEOMETRY 1. The ratio in which the line segment joining A(-2, -3) and B(3, 7) is divided by the y-axis is 3 : 1 1 : 2 2: 3 1 : 3 2. If the distance of the point P(x, y) from the point A(5, 1) and B(-1, 5) are equal then 5x = y y = 5x 3x = 2y 2x = 3y 3. The perpendicular distance of A(5, 12) from y-axis is 13 units 17 units 5 units 12 units 4. If origin is the centroid of a triangle whose vertices are A(a, b), B(b, c) and C(c, a), then the value of a + b + c is 0 2 3 1 5. If the vertices of a triangle are (3, 75), (-7, 4), (10, -k) and its centroid is (k, -1), then k= 4 k= 3 k= 2 k= 1 6. If a line is drawn through (4, 6) parallel to the x-axis, then the distance of this line from the x-axis is 2 units 4 units 6 units 10 units 7. A circle drawn with C(2, – 4) as the centre passes through (5, – 8). The point which does not lie in the interior, of the circle is (2, 0) (9, 4) (- 1, – 4) (1, -3) 8. If the points (0, 0), (1, 2) and (x, y) are collinear, then 2x = y x = 2y x = y 2x = – 4y 9. The distance between the points P(6, 0) and Q(-2, 0) is 8 units 6 units 4 units 2 units 10. The points (- 5, 0), (5, 0), (0, 4) are the vertices of a right triangle an equilateral triangle a scalene triangle an isosceles triangle Loading … Question 1 of 10
