Here, we want to use the graph to check that the ratios are equivalent

To do this, we need to establish that there is a linear relationship between the width and the length

We identify the points given and plot them on the graph

After plotting, we join the points with a straight line passing through the points

Now, after joinin the points with a straight line, we identify the length 20 and trace it to the line. At the point that it touches the line, we get the corresponding width value

We do same for the length 10

Then we fill in the values on the table, then reduce the terms to the lowest values

We will deduce that the lowest value for the points we got through th graph will be the same as that already on the table

Then, with this we can conclude that the ratios are equaivalent and we have succeeded in using the graph to show this
