The slope is 1/4.


With a linear function, finding the slope is the easiest if you think about it as the ratio of the 'change in y' to the 'change in x'.

You can see that from #(7, 2)# to #(3, 1)# the y value decreases by 1, and the x value decreases by 4. So, the slope is the ratio of #(-1)/-4#, which is just #1/4#
