Which ordered pair is part of the equation y = 3x -4? a. (1,1) b. (2,2) c. (3,6) d. (4,9)

I substituted the ordered pairs into the equation.

(1,1)

1 = 3 * 1 - 4  The equation equals -1 for the y, this ordered pair does not
(y)      (x)       make this equation true.

(2,2)

2 = 3 * 2 - 4  This equation equals 2 for the y, this ordered pair makes this 
(y)      (x)       equation true.  

(3,6)

6 = 3 * 3 - 4  This equation equals 5 for the y, this ordered pair does not 
(y)       (x)     make this equation true.

(4,9)

9 = 3 * 4 - 4  This equation equals 8 for the y, this ordered pair does not
(y)      (x)       make this equation true

So I would go with B. (2,2)

3cm and 6 and 9 cm that a possibility of that question
