Write the coordinates of the point which – (a) Lies on the X-axis and is at a distance of 4 units to the right of the origin. (b) Lies on the Y-axis and is at a distance of 5 units below the X-axis.
Answers
a. if the point lies on x axis then the value of ordinate(y axis) is 0
and the distance of the point is 4 unit to the right of origin means it is positive.
so the coordinates of the point is (4,0)
b. if the point lies on y axis then the value of abscissa(x axis) is 0
and the distance of point is 5 unit below the x axis means it is negative 5.
so the coordinates of the point is (0,-5)

Answer:
coordinates of point (a) (4,0)
coordinates of pont (b) (0,-5)
EXPLANATION
Every point on the x-axis is at a distance of 0 unit from the x-axis.So it's ordinate is 0.
Every point on the y-axis is at a distance of 0 unit from y-axis.So it's abscissa is 0.
right of the origin represent positive sign of abscissa
So,coordinates of point (a) (4,0)
below of origin represent negative sign of ordinate
So,coordinates of pont (b) (0,-5)
