The steepness of a line graph is called the "gradient" ------------------------------- or slope.
If the graph is a function, no line perpendicular to the X-axis can intersect the graph at more than one point.
manipulated variable
Some do and some don't. It's possible but not necessary.
It is sometimes called the gradient.
The Orgin
The Orgin
It is simply called a point on the graph, or a solution to the equation represented by the graph.
It marks the origin - the point where the horizontal and vertical axes cross.
On the Cartesian plane it is at point of origin whose coordinate is (0, 0)
The vertex is the highest or lowest point on a graph.
It is called a coordinate.
The origin
A coordinate !
A point on a graph, when all nearby points have a smaller value, is called a maximum.
equilibrium
A point of intersection.
