If two linear functions y = K1 + B1 and y = K2 + B2 intersect at the same point on the Y axis, then for the conclusion: ① K1 = K2; ② B1 = B2 One of them must be true Neither a, B, C, nor D

B
Are you missing two X's

The linear L1: y = K1X + B1 and the linear L2: y = K2 + B2 are known
(1) When --, L1 and L2 intersect at a point;
(2) When --, L1 / / L2, then the solution of the system {y = K1X + B1; y = k2x + B2} is --;
(3) When --, L1 and L2 coincide, the solution of the system {y = K1X + B1; y = k2x + B2} is --
[the answers should be complete and clear. If necessary, write down the reasons or the process of solving the problem]

It should be y = K1X + B1, y = k2x + B2
(1)、k1≠k2
(2) K 1 = K 2, B 1 ≠ B 2, the equation has no solution
(3) K 1 = K 2, B 1 = B 2
