Joaquin is right, as the inequality does not express an inclusion of x=7 in the graph.
It says it is "greater than 7", not "greater than or equal to 7".
The unit rate for A is 5 because 25/5 = 5 and Unit rate for B is 4 because 24/6 = 4 and your asnwer would be A because it’s moving more at shorter speed. Could I have brainliest because I need one more to get a new rank
