Question

Which of the ordered pairs below satisfy the following equation?

Check all that apply.

y = 7x

A. (84, 12)
B. (42, 7)
C. (12, 84)
D. (84, 14)
E. (6, 42)
F. (42, 6)

Answer 1

So you have many ordered pairs here that look like (x , y)

So you take each one, for example (84,12) and plug it into that equation you have

\[\large y = 7x\]

(84 , 12) means (x = 84, y = 12 ) so we plug those in

\[\large 12 = 7(84)\]

Does that come out true? if it doe...we have a solution..if not...obviously not :)
