Want this question answered?
the coordinate plane is a map of points
All points whose y-coordinate is twice its x-coordinate.
Most functions are continuous (connected line), and not just two points... 2 points are simply just coordinates on a graph, and would be very hard (perhaps impossible) to make into a function (unless you have a restricted domain) I may be wrong, but I don't think I am A function has to be a graph that can be expressed through an equation, and only has a max of one y coordinate for each x coordinate, although it may have zero
It describes points on a plane.
Y-axis is the set of all points with x coordinate zero.
Scale factor
Cartesian coordinate system
If the reference points are not correct, the location of any coordinate will be incorrect.

A graph that is not a function, fails the vertical line test. You can draw it by connected all ordered pair of points in a rectangular coordinate system.

Trianglles are the geometric figure consisting of three points called vertices,connected by three sides........
