Question

Draw the graph on the equation represented by a straight line which is parallel to the x-axis and at a distance 3 unit below it

Answer 1

Please find the attached diagram.

We know,

The equation of line parallel to the x- axis, y=a

And a is distance with respect to x- axis.

So, a= -3

Therefore, the equation of straight line, y= -3

Answer 2

Step-by-step explanation:

Consider the provided information.

We need to draw the straight line which is parallel to the x axis.

The equation of line which is parallel to x axis is: $y = b$

Here b is the distance from x-axis.

As it is given that distance is 3 unit below the x axis.

If a straight line at a distance b is parallel and above x-axis, its equation will be y = b.

If a straight line at a distance b is parallel and below x-axis, its equation will be y = -b.

As distance is 3 unit below the x axis use negative sign as shown.

$y = -3$

Therefore, the equation of line is $y = b$.

Draw a line parallel to x axis and passing through the coordinate (0,-3).

The required graph is shown in figure 1.
