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:
 [tex](x, y) = (-1, 1) [/tex]
 Answer:
 C (-1, 1)

 Part 2:

 For this case we have the following linear function:
 [tex]y = x - 4 [/tex]
 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:
 [tex]-5 = -1 - 4 [/tex]
 Rewriting:
 [tex]-5 = -5 [/tex]
 Both sides of the equation are equal and therefore the point belongs to the function.
 Answer:
 A (-1 -5)
