Answer:

b. (2,0)

Explanation:

To find which ordered pair is a solution, we have to replace then into the equation, and the result has to be an identity, that is, 0 = 0.

Equation:


y = -5x + 10

Option a:


(-15,5), so
x = -15, y = 5


y = -5x + 10


5 = -5(-15) + 10


5 = 75 + 10


5 = 85

Not an identity, so this ordered pair is not a solution.

Option b:


(2,0), so
x = 2, y = 0


y = -5x + 10


0 = -5(2) + 10


0 = -10 + 10


0 = 0

Identity, and thus, the correct answer is given by option b.
