# Acceleration time graphs and velocity time graphs

i have an acceleration time graph and need to create a velocity time graph. i know to get the velocity you take the area under the acceleration graph but i don't understand how you get the lines.

eg. a speed boat accelerates at 2m/s^2 for 7.0 seconds.

on the acceleration time graph i believe this would be a line parallel to the x axis at 2on the way axis. how do i convert this line to a line in the velocity time graph?

find the area under the graph in the first 1 second, then the area in the first 2 seconds (from 0 to 2), and so on up to the first 7 seconds (0 to 7)

then plot those figures against t = 1, 2, … 7 (on the t axis)
