Question

If y = 8x − 2, which of the following sets represents possible inputs and outputs of the function represented as ordered pairs?

{(0, −2), (1, 6), (2, 14)}
{(0, −2), (2, 13), (−5, −40)}
{(1, 7), (2, 7), (3, 7)}
{(1, 6), (2, 13), (3, 24)}

Answer 2

each of those pairs is a point (x,y)

test all 4 points, they all have to satisfy y = 8x - 2

Answer 3

so, whats the answer?

Answer 4

For example the first one...
(0 , -2) -2 = 8*0 -2 true
(1 , 6) 6 = 8*1 - 2 true
(2 , 14) 14 = 8*2 - 2 true

The first set of points works

Answer 5

A?

Answer 6

First one is the answer

Answer 7

Yes

Answer 8

A works, not sure about the others if more

Answer 9

Only a works. I did it.
