Question
Write the joint equation of co-ordinate axes.
Advertisements
Solution
As we know that,
- In the coordinate axes, on the x-axis, the value of y always stays constant and the value of x keeps changing.
- Similarly, on the y-axis, the value of x stays constant and the value of y keeps changing.
Here,
Equation of coordinates,
for x-axis,
y = 0 `\implies` equation (1)
for y-axis,
x = 0 `\implies` equation (2)
now,
To get the combined equation we will multiply equations (1) and (2).
xy = 0
Hence the joint equation of coordinates axes is xy = 0
