PLEASE HELP
WILL FAN AND MEDAL!
If y = 5x − 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
{(2, 5), (−3, −12), (−4, −18)}
{(−1, −8), (0, −3), (3, 12)}
{(1, 4), (7, 25), (3, 10)}
{(5, 20), (6, 12), (1, 9)}

Answer 1

you want me to explain how to do it, or do it for you?

Answer 2

both kinda?

Answer 3

alright.

Answer 4

this might take a few minutes

Answer 5

k

Answer 6

take the original equation y=5x-3, and you need to plug all of those sets in to see if they apply to the origin

Answer 7

the first set, plug in 2 for x and 5 for y, and let me know what yop got

Answer 8

10, 15????????

Answer 9

no, plug them in like this. y=5x-3 so that 5=5(2)-3

Answer 10

plug them in like youre checking points on a graph

Answer 11

?

Answer 12

just o you know, i workrd it out, its the second one. but you still need to understand why

Answer 13

ok, look. ill just show you why it is the second one, ok?

Answer 14

the first set is (-1,-8), so we must plug it in to see if it works. plug in -1 for x and -8 for y

-8=5(-1)-3
