Part 1:
For this case we first define the variables:
x: independent variable (horizontal axis)
y: dependent variable (vertical axis)
We have then that the next ordered pair belongs to the shaded region:
Answer:
C (-1, 1)
Part 2:
For this case we have the following linear function:

We must find an ordered pair of the form (x, y) that satisfies the equation.
We have then:
For (-1, -5):
Substituting in the equation we have:

Rewriting:

Both sides of the equation are equal and therefore the point belongs to the function.
Answer:
A (-1 -5)
