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
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)
3 answers
Both ordered pairs at D satisfy the Eq .
good job
