y  =  -1/2 x - 3

 

The point where the line crosses the  y-axis  is the point where  x = 0 .

So, plug in  0  for  x  and solve for  y .

 

y  =  -1/2 (0) - 3

                                       And  -1/2 * 0  =  0 .

y  =  0 - 3

 

y  =  -3

 

When  x = 0 ,  y = -3 .    That gives us the point  (0, -3) .
