Question

15. Point (-1,0) lies in the: (a) on the negative direction of x - axis (b) on the negative direction of y- axis (c) in the III quadrant (d) in the IV quadrant ​

Answer 1

Option A
As we move towards the left we get negative values of x.

Answer 2

Answer:

A) On the negative direction of x-axis

Step-by-step explanation:

The equation of a point on the x-axis is ‘y = 0’. X can take any value.

Always remember, that the distance away from the x-axis must be 0 for the point to be on the x-axis. Thus, y = 0.

By convention, any ordered pair is in the form (x,y).

Here, it is (-1,0). So, y = 0.

For the point to be in the negative direction of x - axis, the value of the x-coordinate must be a negative real number. Here, the value of the x-coordinate is ‘-1’, which is a negative real number.

Thus, according to the proof given above, the point (-1,0) lies on the negative direction of the x-axis.
