How do I find velocity when given acceleration and time on a graph? Thanks

I have a question for you, are you proposing theses several questions because you do not know or because you want to see if anyone else actually knows. How are the two axis of the graph labeled?

I'm asking because I have no idea. It's for homework. Anyway the x-axis has time and y-axis has acceleration m/s^2... thanks

velocity will be changing/increasing all along the line on the graph, you must pick a particular point and say what is the velocity at this x/y

Do you know how to differenciate and integrate?

If you differenciate a distance-time curve, you get a velocity-time curve.
If you differenciate a velocity-time curve, you get an acceleration-time curve.

The other way round;

If you integrate an acceleration-time curve, you get a velocity-time curve.
If you integrate a velocity-time curve, you get a distance-time curve.

All these processes are with respect to time.

[differenciating a curve with respect is plotting its gradient against the time. The rate of change of distance is speed. Plotting the gradient of distance against time gives the velocity-time graph. So, if you have a distance-time graph with gradient 2 everywhere, you will have a velocity-time graph as a straight horizontal line with intercept at velocity=2. The same goes for acceleration if you have a velocity-time graph with gradient 2 throughout]
