Question

Which ordered pairs are solutions to the equation?

y = 3x – 4

A.
(11, 5) and (2, 2)

B.
(5, 11) and (3, 2)

C.
(5, 11) and (2, 3)

D.
(5, 11) and (2, 2)

Answer 1

Basically, you are switching the 'x's and the 'y's, and then isolating to solve for x:

x= 3y-4

3y= x+4

y= (x+4)/3

Therefore y^-1 (that's how you write inverse) =(x+4)/3

Answer 2

Both ordered pairs at D satisfy the Eq .

Answer 3

good job
