Answer:
The ordered pair is a solution to the equation
Step-by-step explanation:
Plug the ordered pair into the equation as (x,y):
y = -x + 8
4 = -4 + 8
4 = 4
Since both sides are equal to each other, then the ordered pair is a solution to the equation.
Its C.
Negative x Negative is positive, so its not A or D.
Positive x Positive is Positive, so its not B either.
C is your option because Positive x Negative is Negative, and vice verca.
