Question

Help me plz have a blessed day

Answer 1

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.
