How can we convert a distance/time graph (that also contains a table of info) into velocity/time, using the two point method?

What is the relationship between "velocity" and "distance"?

'd' is displacement 've
you'll learn it afterward perhaps i see

i am giving you graph of speed vs time

if d-t graph is straight line at an angle α with x axis then v-t graph is a line parallel to x axis
if d-t graph is parabolic then v-t graph is straight line at an angle θ with x axis

Not quite.

You need to know that velocity is the time rate of change of displacement/position. In graph form, it corresponds to the slope at a given point in the displacement-time graph.

You should have enough here to answer the question.

Note that you need to know the physical meaning of all of this. It is not enough to just know/memorize the equation without understanding what it means.
