Yes, it matters.
yOU START WiTH THE VERTEX.VERTEX iS THE ANSWER
The slope for a line between two points is (difference of y-coordinates) divided by (difference of x-coordinates). That is, (y2-y1)/(x2-x1). It doesn't matter in what order you take the points.
vertex* * * * *Yes.
If cartesian coordinates are used then the second number in an ordered pair is the y coordinate, also known as the ordinate. If polar coordinates are used then the second number is the angle.
yes because it important to use it in mid point formula
get them from j6 located in the saloon. you have to complete his little quiz in order to get coordinates.
Coordinates
yes, it does
Its function naming and parameter order/return values are inconsistent

A pair of coordinates

It terms of the order in which the coordinates are given, yes.
