In the plane rectangular coordinate system, the image of the function y = (2a-1) x + A + 3 passes through the origin, and the value of a is obtained

In the plane rectangular coordinate system, the image of the function y = (2a-1) x + A + 3 passes through the origin, and the value of a is obtained

The analysis is as follows
Known function expression, and through the origin
explain:
Substituting the point (0,0), the equation holds
So a + 3 = 0 gives a = - 3
