Ex 3.3, 1
In which quadrant or on which axis do each of the points (-2,4), (3,-1), (-1,0),(1,2) and (-3,-5) lie? Verify your answer by locating them on the Cartesian plane.
(-2,4)
x-coordinate is negative,
y-coordinate is positive
So, ( 2, 4) is in II quadrant
(3,-1),
x-coordinate is positive,
y-coordinate is negative.
So, (3 , 1) is in IV quadrant
(-1,0)
x-coordinate is negative,
y-coordinate is zero
So, ( 1, 0) lies on negative x -axis
(1,2),
x-coordinate is positive,
y-coordinate is positive
So, (1, 2) is in I quadrant
( 3, 5),
x-coordinate is negative,
y-coordinate is negative
So, ( 3 , 5) is in III quadrant
Now, we plot points ( 2,4) , (3, 1), ( 1, 0), (1, 2), ( 3, 5) on graph
Now, we plot points ( 2,4) , (3, 1), ( 1, 0), (1, 2), ( 3, 5) on graph
( 2, 4) is in IInd quadrant
(3, 1) is in IVth quadrant
( 1, 0) is in negative x-axis
(1, 2) is in Ist quadrant
( 3, 5) is in IIIrd quadrant
