On a number line does 2 or - 2 represent the absolute value of -2?
It is simply the difference between their y coordinates.
Simply divide the difference in the y-coordinates, by the difference in the x-coordinates.
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
Points: (-3, -1) and (3, -2) Slope: -1/6
If you have the coordinates of two points, say P = (a,b) and Q = (c,d), then slope = (b-d)/(a-c) that is, the difference in the y coordinate of the two points divided by the difference in the x coordinate of the points taken in the same order.
The distance between any two points on a number line is the absolute value of the difference of the coordinates.

It is simply the difference between their y coordinates.
It is simply the difference between their y coordinates.
The distance between them is the absolute value of the difference in their vertical coordinates.
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
The distance between two points on a line is the absolute value of the difference between their coordinates. This can be calculated using the distance formula: |x2 - x1|, where x1 and x2 are the coordinates of the two points.
The Minkowsky or Taxicab distances.
To find the distance between two points on a segment, you subtract their coordinates and take the absolute value of the result. This gives you the length of the segment between the two points. For example, for points ( A(x_1, y_1) ) and ( B(x_2, y_2) ), the distance in one dimension would be ( |x_2 - x_1| ) for the x-coordinates, or ( |y_2 - y_1| ) for the y-coordinates. In two dimensions, you would use the distance formula, which incorporates both coordinates.
All complex number that can be represented by the coordinates of points on the unit circle, that is, the circle with its centre at the origin and a radius of 1 unit.
The difference in the X-coordinates (in the X-axis (horiztontal(left-right))) of two points is called the "run".
