For the first question, we can substitute the x and y values of each coordinate pair into the equation y = -14x - 3 to see if they satisfy the equation:
A) (-8, -1): y = -14(-8) - 3 = 113 - 3 = 110 (not a solution)
B) (-2, -4): y = -14(-2) - 3 = 29 - 3 = 26 (not a solution)
C) (4, -4): y = -14(4) - 3 = -56 - 3 = -59 (not a solution)
D) (0, -3): y = -14(0) - 3 = 0 - 3 = -3 (a solution)
Therefore, the coordinate pair that is NOT a solution for the equation is A) (-8, -1).
For the second question, we are given that x = -4, so we can substitute this value into the equation y = -14x - 3 to find the y-coordinate:
y = -14(-4) - 3 = 56 - 3 = 53
Therefore, the y-coordinate for the solution with x = -4 is 53.
