Please help me, please.

Answer:
slope = 2
Explanation:
by the formula y1 - y / x1 -x we can find the slope of the graph
here lets take coordinates : ( 4 , 8 ) and ( 0, 0)
using the formula : ( 0 - 8 ) / ( 0 - 4 ) = 2
Answer:
Acceleration
Explanation:
Slope can be found by taking two points in graph (x1,y1),(x2,y2)
Slope formula is
As
Acceleration=dv/dt
The unit comes
