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.
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 vertical line goes straight up an down, so a vertical line segment is a line segment that goes straight up and down. Simple.
for example a straight line.(is it straight up and down)
