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

 

(1) (2,9),2x+9y=85

 

(2) (8,7), y=-1/4x +5

Answer 1

Just plug numbers in, first for x, second for y. If the equality is true, the pair is the solution. If you do it, you will see that one pair is the solution, whereas another one is not. You figure out which one yourself.
