Given the point (3, 3.5), name a second point so that the two points form a horizontal segment.
Sati [7]

For the horizontal segment, the value of the ordinate will not change. Then the second point will be (x, 3.5).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The point is given as (3, 3.5).

Then name a second point so that the two points form a horizontal segment.

For the horizontal segment, the value of the ordinate will not change.

Let x be the abscissa.

Then the point will be given as (x, 3.5).

More about the coordinate geometry link is given below.
