Question

In the XY-plane, the X-axis contains all ordered pairs such that:

Answer 1

Answer:

B) The y-coordinate is 0

Step-by-step explanation:

We are given that,

'In an x-y plane, the x-axis consists of all the ordered pairs of the form (x,y)'.

It is required to find the condition on the ordered pairs.

Since, we know that,

On the x-axis, the value of y= 0.

So, 'x-axis contains the ordered pairs of the form (x,0)'.

Thus, option B is correct.

Answer 2

Answer:

Option B

y coordinate is 0

Step-by-step explanation:

We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.

X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0

To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.

Thus we have along x axis, y values to be 0

Hence any point on x coordinate will be of the form (a,0) where a can be any real number

So option B is right
