Question

Find three solutions of 9x – 2y = 18.


A. (0, 0), (9, 2), (2, 9)

B. (0, –2), (9, 0), (9, –2)

C. (0, 2), (–9, 0), (1, 7)

D. (0, –9), (2, 0), (1, –4.5)

Answer 1

Try to replace the values (0,0), (9,2), etc in the equation (x and y, respectively) and see if you get an true equality.

Answer 2

For instance: replacing (0,0).
9x - 2y = 18
9*0 - 2*0 = 18
0 = 18
So first option is false.

Answer 3

That's not the true way of doing it.
