Question

Please help!!!
Does the following set of ordered pairs satisfy a linear function? {(1, 8), (2, 6), (3, 4), (4, 2), (5, 0)}
A:No, there is no constant change of x corresponding to y.
B:Yes, there is a constant change of +1for x which corresponds to a constant change of -2 in y.
C:Yes, the x values are larger than the y values.
D:No, there is no correlation between x and y.

Answer 1

yes, because every input only has 1 output

Answer 2

simply put, if a graph passes the horizontal line test, then it is a function

Answer 3

so is it b or c? haaha

Answer 4

B, because for C, just because the x values are larger does not mean it is a function. it can have a negative slope where the x is lower than y and it is still considered a lin function

Answer 5

thanks
