Question

The slope of the line passing through (4,3) and (2,3) is coming out as 0/2=0 does this mean that the line lies on the x-axis? If not then what's the reason? Slope as 0 means there must not be any inclination with the x-axis. Therefore either it should be parallel. Then why is it showing the x axis values as 4 and 2 it should be 0.

Answer 1

A horizontal line has slope 0 because all its points have the same y-coordinate.

Because the point has no inclination with respect to x axis.

Here both the points have same y same y coordinate.
That means, the line is horizontal, or it is parallel to x axis.

So it have a zero slopeslope.
