y = 4x - 3    substitute it to the second equation y = -x - 13:

4x - 3 = -x - 13       add 3 to both sides

4x = -x - 10       add x to both sides

5x = -10       divide both sides by 5

x = -2

Substitute the value of x to the first equation:

y = 4(-2) - 3

y = -8 - 3

y = -11

Answer: B: (-2, -11)
