The function y = 4x + B, the area of the triangle formed by its image and two coordinate axes is 16, then the value of B is_____ . The function y = 4x + B, the area of the triangle formed by its image and two coordinate axes is 16, then the value of B is_____

Constant over (0, b), (- B / 4,0)
b*b/4*1/2=16
B = + / - 8 root sign 2
