What is horizontal

We can see that, there is no change in the y point on a horizontal line. The horizontal line continues straight left or right. Thus, the slope of a horizontal line is 0. Considering the previous image, we can see that the y-coordinates of all the points on a horizontal line are the same. Here x is absent. It means that the x-coordinate can be anything whereas the y-coordinate of all the points on the line must be 'b' only. The y-intercept of the horizontal line is 0, b.

Considering the previous image points a,b : 2, -3 , 1, -3 , -2, -3 We can see that the y-coordinate of all these points is constant, which is The horizontal line test is used to determine whether a function is a one-to-one function. According to the horizontal line test, a function is NOT one-to-one if there exists a horizontal line that passes through more than one point of the graph of the function. In other words, in a one-to-one function, there is only one unique x-value for every y-value.

In the first image, f x is one-to-one because every horizontal line passes through at most one point of the graph. In the second image, g x is not one-to-one as the horizontal line that passes through more than one point of the graph. Horizontal means "side-to-side" hence horizontal line is a sleeping line, whereas, vertical means "up-to-down" therefore a vertical line is a standing line.

Horizontal lines are lines drawn from left to right or right to left and are parallel to the x-axis. Vertical lines are lines drawn up and down and are parallel to the y-axis. Something, such as a line, plane, or object, that is horizontal. At, or made up of elements at, the same levels of industrial production and distribution, or of status.

Of or near the horizon. A horizontal line, plane, etc. Position parallel to the horizon. Relating to or near the horizon. Perpendicular to the vertical ; parallel to the plane of the horizon; level , flat.
