How do you find the equation of a straight line?
why would you find the equation of the straight linr- the gradient doesn't give the speed could you please lemme know?

Part (i) - did you get an answer?
part (ii) you need to find the equation for the accel in terms of t ... y = mx + c with c = 0 as the line passes through the origin.

Apologies, I just read second part and thought you meant part ii.

But can you not do (v-u)/t =a as the acceleration is the change in velocity so since u=0 and t=4 and a=8 I did (v-0)/4 =8 so v=32 but the answer is 16 Could you please let me know where I went wrong?

Acceleration is not constant and it needs to be to use that equation.
Do you know the answer to the question I posed?

does it represent velocity? or velocity change actually I am not sure could you please let me know?

Here it will be velocity and give you what you are looking for.
