Which order pair is a solution of this equation? -3x-7y=4
1 answer:
Answer:
(-6,2)
Step-by-step explanation:
An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.
-3x - 7y = 4
Substitute:
-3(-5) - 7(2) = 4
15 - 14 = 4
1 = 4 FALSE
-3(2) - 7(-5) = 4
-6 + 35 = 4
29 = 4 FALSE
-3(2) - 7(-6) = 4
-6 + 42 = 4
36 = 4 FALSE
-3(-6) - 7(2) = 4
18 - 14 = 4
4 = 4 TRUE
