To check which of the given coordinate pairs satisfy the equation -3x*y = -4, we can substitute the values of x and y into the equation and see if it holds true. Let's check each coordinate pair one by one:
1. (5, 1):
-3 * 5 * 1 = -15 ≠ -4
2. (1, -5):
-3 * 1 * -5 = 15 ≠ -4
3. (5, 1):
-3 * 5 * 1 = -15 ≠ -4
4. (1, 5):
-3 * 1 * 5 = -15 ≠ -4
None of the given coordinate pairs satisfy the equation -3x*y = -4.
