Given the question, it needs the points so that the equation can be evaluated and to know if the points is a solution to the equation or not.
First, change the fractions into decimals. 7 3/4 changes to 7.75 and -7 2/3 changes to -7.66. And then order up the numbers from least to greatest. That will be -7.66(-7 2/3), then -7.3, then 7.23, and then 7.75(7 3/4)
