From the way the question is phrased, it seems safe to assume that you have the coordinates of the points.
If the points are on a number line (a single number describes each point), subtract one number from the other. Take the absolute value of the result.
If the points are in two or three dimensions - meaning that you need two or three coordinates to specify each point - you can use the Pythagorean Theorem. For example, in two dimensions, for points (x1, y1) and (x2, y2), you calculate:
square root of ((x2 - x1) squared + (y2 - y1) squared)

How do you find coordinates of two points to find distance between them?
Use the distance formula. SQRT( (y1-y2)^2 + (x1-x2)^2) ) x1 and y1 are the first coordinate pair x2 and y2 are the second coordinate pair
What coordinate is used to locate points on grids?
Not a coordinate but a pair (or larger set) of coordinates.These are ordered sets of numbers that give the distance of the point, from the origin, along each of the axes in multidimensional space.
What is the coordinate of the point halfway between each distinct pair of points on a number line?
It is the arithmetic mean of the two numbers. The halfway point between x and y is (x + y)/2
What are two endpoints and all of the points between them called?
A line segment (sometimes just segment) is a pair of endpoints and all the points on a line between them.
What is the locus of points 1 cm from a given line Q?
A pair of parallel lines at a distance of 1 cm from the line Q.
