## Main Question or Discussion Point

Hello I plotted a graph of velocity against time only to realise that I needed more space on the X axis, so I changed my scale from instead of 2cm= 10 seconds to 2cm =20 seconds.

My Y axis remained constant with a scale of 2cm= 10 m/s

However, the gradient I got from the first scale was 1.15m/s

But with my new readjusted scale to fit the page I'm getting a gradient of 2.4 m/s

How can this be? the graph is a straight line so the acceleration is constant according to the data given, am I plotting this wrong??

^{2}and this even coincides with the data given.But with my new readjusted scale to fit the page I'm getting a gradient of 2.4 m/s
