✔ 最佳答案
acceleration a=(12-6)/3=2 ms^-2so
the graph is
two point at (0,6) (3,12) respectively
draw them with a straight line
the slope should be 2

應該0甘寫draw a straight line pass throught (0,6) (3,12)

the unit of x-axis is t/sthe unit of y-axis is v/ms^-1

畫s-t，y是speed/ms^-1，x是t/s
點上兩點，（0，6）和（3，12），用尺子連起這兩點。
