3. Coordinate Geometry
easy
In which quadrant or on which axis does each of the following points lie?
$A (15,-10), B (-10,-20), C (25,0), D (-15,25)$ $E (-5,0), F (0,-15), G (25,5), H (0,15)$
Verify your answer by plotting the points in the Cartesian plane. Use the scale $1\, cm =5$ units on both axes.
Option A
Option B
Option C
Option D
Solution
Points | Position of the point | |
$A(15,-10)$ | In the fourth quadrant | |
$B(-10,-20)$ | In the third quadrant | |
$C(25,0)$ | On the $x -$axis | |
$D(-15,25)$ | In the second quadrant | |
$E(-5,0)$ | On the $x -$axis | |
$F(0,-15)$ | On the $y -$axis | |
$G(25,5)$ | In the first quadrant | |
$H(0,15)$ | On the $y$ -axis |
