How to calculate the slope of position time graph ?

Slope=

Explanation:

We are supposed to find the slope in a position time graph,

For that we need atleast two points .( represents there coordinates in respective axis directions.)

In the given case the y axis would be the position and the x axis as time .

Slope is defined as the ratio of change in y coordinate to change in x coordinate :-

So subsituting the coordinates of position and time we get slope as:-

[When we have more than two points which are not collinear then to calculate the slope we take the average.]
