SOLUTION: For what value(s) of k will the relation not be a function? R = {(k�8.3+2.4k, −5), (−3/4k, 4)}

Question 1100840: For what value(s) of k will the relation not be a function? R = {(k�8.3+2.4k, −5), (−3/4k, 4)}

When the two x coordinates are equal, it won't be a function, since they would have two different outputs for the same input.
k-8.3+2.4k=-(3/4)k
4.15k=8.3
k=2 ANSWER
when k=2, the x coordinates are -1.5 and -1.5
