A science teacher carried out an experiment measuring the time it took for a block to slide different distances down a ramp. Two of her students, Courtney and Jeremiah, plotted the results on scatter graphs with different axes.
The points on Jeremiah's graph lie on a curved line and the points on Courtney's graph lie on a straight line, as shown below.
a) Use the line of best fit on Courtney's graph to estimate the time, in seconds, that it would take the block to slide 4 m .
b) Write a sentence to explain why it is less accurate to use Jeremiah's graph to estimate the time it would take the block to slide 4 m .
