Question

20 POINTS

For each ordered pair, Determine whether it is a solution of the system of equations.

Answer 1

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Answer 2

No

No

Yes

Yes

Explanation:

8x + 2(-4x - 5) = -10

8x - 8x - 10 = -10

-10 = -10

Infinite solutions

-3 = -4(-2) - 5

-3 = 3 (false)

1 = -4(6) - 5

1 = -29 (false)

-5 = -4(0) - 5

-5 = -5 (true)

15 = -4(-5) - 5

15 = 15 (true)
