Question

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)}

Answer 1

so, which ordered pairs are solutions right?

Answer 2

Yes I think so

Answer 3

if so then we just plug them in to check :)

Answer 4

does 1,-1 fit?

Answer 5

I'd have to get out paper and pencil.

Answer 6

paper and pencil are fine; but lets try this approach:

5(1) -2(-1) = 6

Answer 7

does 5 + 2 = 6 ?

Answer 8

no

Answer 9

then c and d are out

Answer 10

a nad b differ by sat (0,-3) so if that fits its b, if not its a

Answer 11

5(0)-2(-3) = 6 ?

0 + 6 = 6 ?

Answer 12

yeah

Answer 13

a and b differ by say .... typing aint my forte :)

then since b fits, lets use b :)

Answer 14

since there is no "none of the above" option I assume it has to be one of those posted, so "b" seems the best candidate

Answer 15

alright thanks!!
