Question 251100: You are given this formula: R = {(5k + 3, 4), (3k - 5, 7)}. Which equation would find the value for k that makes this relation not be a function?
a. 5k + 3 + 4 = 3k - 5 + 7
b. 5k + 3 = 3k - 5
c. 5k + 3 + 3k - 5 = 4 + 7
d. 5k + 3 - 4 = 3k - 5 - 7

B
In a function, every x maps to one and one only value of y.
You are given two points. The y coordinate of one point is 4 and the other is 7. If the same value for x maps to both 4 and 7, then the relationships is NOT a function.
So 5k+3 must not equal 3k-5. If those two things are equal, then no function.
