I do believe that that point is -2.2 because of the fact that the difference between -1.6 and -2.4 is 0.8, and there are 4 marks in between them. So each mark's value is decreased by -0.2.
<h2><em>-2.2</em></h2><h2><em>This is because going to the right the A is the -2.2 and the space between -2.4 and -2.2 is -2.3.</em></h2><h2><em>Hope this helps, sorry if not tho</em></h2>
