Liner Equation....................................

Question

Liner equation with 2 variable question Is this ordered pair a solution of this given equation?

 

(5,-2),-x+7y=-9

Answer 1

If (5, -2) is a solution of the equation, then when you substitute 5 for x in the equation and -2 for y in the equation, you should get a true statement.

 

For instance (3, 2) is not a solution because

-3 + 7(2) does not = -9

 

In your problem, does, -5 + 7(-2) = -9?
