Without the specific graph to refer to, we cannot determine which coordinate pair is not a solution for the equation y = -1/4x - 3. Please provide the specific graph or another piece of information to make a determination.

For the equation y = -1/4x - 3, let's evaluate each coordinate pair to determine which one is not a solution.
A: (-8, -1)
Plugging -8 into the equation, we get:
-1 = (-1/4)(-8) - 3
-1 = 2 - 3
-1 = -1
Since the equation is true, (-8, -1) is a solution for the equation.
B: (-2, -4)
Plugging -2 into the equation, we get:
-4 = (-1/4)(-2) - 3
-4 = 1/2 - 3
-4 = -5/2
Since the equation is false, (-2, -4) is not a solution for the equation.
C: (4, -4)
Plugging 4 into the equation, we get:
-4 = (-1/4)(4) - 3
-4 = -1 - 3
-4 = -4
Since the equation is true, (4, -4) is a solution for the equation.
D: (0, -3)
Plugging 0 into the equation, we get:
-3 = (-1/4)(0) - 3
-3 = -3
Since the equation is true, (0, -3) is a solution for the equation.
Therefore, the coordinate pair that is not a solution for the equation y = -1/4x - 3 is (−2, −4).
For the second question, if -4 is the x-coordinate for a solution to the equation, we can plug it into the equation to find the y-coordinate:
y = (-1/4)(-4) - 3
y = 1 - 3
y = -2
Therefore, if -4 is the x-coordinate for a solution to the equation, the corresponding y-coordinate is -2. The answer is C.
A: (-8, -1)
Plugging -8 into the equation, we get:
-1 = (-1/4)(-8) - 3
-1 = 2 - 3
-1 = -1
Since the equation is true, (-8, -1) is a solution for the equation.
B: (-2, -4)
Plugging -2 into the equation, we get:
-4 = (-1/4)(-2) - 3
-4 = 1/2 - 3
-4 = -5/2
Since the equation is false, (-2, -4) is not a solution for the equation.
C: (4, -4)
Plugging 4 into the equation, we get:
-4 = (-1/4)(4) - 3
-4 = -1 - 3
-4 = -4
Since the equation is true, (4, -4) is a solution for the equation.
D: (0, -3)
Plugging 0 into the equation, we get:
-3 = (-1/4)(0) - 3
-3 = -3
Since the equation is true, (0, -3) is a solution for the equation.
Therefore, the coordinate pair that is not a solution for the equation y = -1/4x - 3 is (−2, −4).
For the second question, if -4 is the x-coordinate for a solution to the equation, we can plug it into the equation to find the y-coordinate:
y = (-1/4)(-4) - 3
y = 1 - 3
y = -2
Therefore, if -4 is the x-coordinate for a solution to the equation, the corresponding y-coordinate is -2. The answer is C.
