Take any two points whose x coordinates are different.Suppose they are P = (Xp, Yp) and Q = (Xq, Yq)
then slope = (Yp - Yq)/(Xp - Xq) = (Yq - Yp)/(Xq - Xp), that is the change in the y coordinate between the two points ("rise") divided by the change in the x coordinate between the points - taken in the same order ("run").
For a straight line, you calculate delta-y divided by delta-x (in other words, difference in y-coordinates, divided by difference in x-coordinates), for two different pointsFor an arbitrary curve, you calculate the derivative. This basically means that you analyze what happens if you choose two points that get closer and closer together.

Calculate slope as slope=(y2-y1)/(t2-t1).
slope = rise divided by run
the formula used to calculate a slope is: m=y2-y1/x2-x1
You cannot: the slope is not defined.
2 ordered pairs are needed to calculate slope.
slope=rise/run in other words: slope= y-axis/x-axis
You need two points before you can calculate the slope.
Points: (-3, -1) and (3, -2) Slope: -1/6

Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
I am not sure what you mean; I guess some symbols disappeared when posting the question. I assume you have two given points. The idea is to calculate the slope as: slope = (difference in y-coordinates) / (difference in x-coordinates)
