x-y=4
The slope of a line can be found by choosing any two points of that single line, not of multiple lines.
To get two points you could shoot a basket because one basket equals two points. Or two free throws.
Yes this true at one point in time
Yes. Any two points are always coplanar.
Any two points are always collinear, since you can draw a straight line passing through any two points.
Any two points have to be on some line.
There is no intrinsic difference. Either can be named using the names of any two points on them, or using any letter or symbol of any alphabet - including symbols that you have made up.
No. Any two points can be made to form a line.
Ohm's Law: Voltage equals Resistance times Current Given any two, you can figure out the other using simple algebra.
== == Through any two points there is exactly one straight line.
Not sure what two non-consecutive points are. No two points are consecutive in the sense that an infinite number of points can be found between any two points.
Yes, two points are always collinear. You can draw a line through any two points.
