1. which ordered pair is a solution of the linear equation shown in the graph above?
a (02, 0)
b(1, 3)
c(-1, 1)
d (0, -1)
2. which ordered pair is a solution of y = x - 4
a(-1 -5)
b (0, -3)
c (2, 6)
d (3,1)

picture is attached, explanation is not expected but is appreciated. you.

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:
 
 
 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.
 
 A (-1 -5)
