Match the following columns:
Column I | Column II |
(a) Equation of x-axis is | (p) (a,0) |
(b) Equation of y-axis is | (q) y = 0 |
(c) Any point on x-axis is of the form | (r) (0,b) |
(d) Any point on y-axis is of the form | (s) x = 0 |
The correct answer is:
A. -…….., B. -…….,
C. -…….., D. -…….,
(a) We know that,
The points that lie on the x-axis have coordinate = 0
∴ The equation of the x-axis will be y = 0
(b) We know that,
The points that lie on the y-axis have abscissa = 0
∴ The equation of the y-axis will be x = 0
(c) We know that,
Any point on the x-axis is of the form (a, 0)
(d) We also know that,
A point on the y-axis is of the form = (0, b)
Hence the correct match for the given table is as follows:
(a) – (q)
(b) – (s)
(c) - (p)
(d) – (r)
