Linear function
Vertical
On a typical graph, the vertical line is the y-axis, they horizontal line is the x-axis.
A vertical line goes up and down otherwise to say it goes straight up
Test it by the vertical line test. That is, if a vertical line passes through the two points of the graph, this graph is not the graph of a function.
Any line that goes straight up and down and doesn't lean either way is a vertical line.
In a speed graph, a straight vertical line represents an infinite speed, which is not physically possible. Such a line would imply that an object is covering a distance instantaneously over a finite time interval, violating the principles of physics. Therefore, a speed graph cannot have a straight vertical line.
The straight horizontal line on a graph is referred to as the x-axis. The vertical line on a graph is the y-axis.
Linear function
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
A vertical line is a line that runs up and down. On a graph, it is either the y axis or parallel to the y axis. It is also perpendicular to the x axis.
up and down it is the y axis on a graph
for example a straight line.(is it straight up and down)
Vertical
A vertical edge is A line that go straight up and down
A straight vertical line down on a distance-time graph indicates that an object is instantaneously returning to its starting point, meaning it has a distance of zero from its initial position at that point in time. This can suggest that the object has stopped moving or quickly changed direction. Since distance cannot be negative, this vertical line reflects a sudden change rather than a continuous movement.
A vertical line goes straight up an down, so a vertical line segment is a line segment that goes straight up and down. Simple.
