Find the solution, given the replacement set.
5x - 2y = 6 {(-2, -8), (0, -3), (1, -1), (2, 4), (4, 7)}
	A.	{(-2, -8), (2, 4), (4, 7)}
	B.	{(-2, -8), (0, -3), (4, 7)}
	C.	{(-2, -8), (0, -3), (1, -1)}
	D.	{(1, -1), (2, 4), (4, 7)}

B.	{(-2, -8), (0, -3), (4, 7)}  

Let's check this one.

directrix · Answer

On second thought, perhaps we should check each of the points in the replacement set.

directrix · Answer

5x - 2y = 6 {(-2, -8)
5(-2) - 2(-8) = 6 ?
-10 + 16 = 6 Yes.

(-2, -8) is in the solution set

directrix · Answer

Will you test (0, -3) while I check out (1, -1)? Will you?

directrix · Answer

(1,-1)

5(1) -2(-1) = 6 ??
5 + 2 = 6
7=6 NOT in solution set.

directrix · Answer

Now, you do ( (2, 4) and I will do (4,7). You can use the drawing tool if you like.

directrix · Answer

(4,7)

5(4) - 2(7) = 6?
20 - 14 = 6 
6=6 YES (4,7) is in the solution set.
