Answer:
[tex] m=\frac{y_2-y_1}{x_2-x_1}\Rightarrow a=\frac {v_2-v_1}{t_2-t_1}[/tex]
Explanation:
The slope of velocity vs time graph gives the acceleration.
[tex] a = \frac{dv}{dt}[/tex]
The equation of uniform velocity time can be written as: y = mx +c
For two points, [tex]y_2=mx_2+c, y_1=mx_1+c[/tex]
[tex] m=\frac{y_2-y_1}{x_2-x_1}\Rightarrow a=\frac {v_2-v_1}{t_2-t_1}[/tex]
