For the first question, we can substitute the x and y coordinates of each answer choice into the equation y = -14x - 3 to see if they satisfy the equation.
A: (-8, -1)
-1 = -14(-8) - 3
-1 = 112 - 3
-1 = 109, which is not true. Therefore, (A) is not a solution.
B: (-2, -4)
-4 = -14(-2) - 3
-4 = 28 - 3
-4 = 25, which is not true. Therefore, (B) is not a solution.
C: (4, -4)
-4 = -14(4) - 3
-4 = -56 - 3
-4 = -59, which is not true. Therefore, (C) is not a solution.
D: (0, -3)
-3 = -14(0) - 3
-3 = -3, which is true. Therefore, (D) is a solution.
Therefore, the coordinate pair that is NOT a solution for the equation y = -14x - 3 is choice (A) (-8, -1).
For the second question, we are given that -4 is the x-coordinate.
We can substitute -4 into the equation y = -14x - 3 to find the y-coordinate.
y = -14(-4) - 3
y = 56 - 3
y = 53
Therefore, the y-coordinate is 53. The correct answer choice is (D) 53.
