Hello I need a bit of help on another math problem please.

Substitute (0,b) into (m or b)=change in y/change in x=Y2-Y1/X2-X1
I am not sure what you would substitute (0, b) into. This does not make sense?

Finally you simplify this equation to arrive at (y=mx, x=my+b, x=my-b, y=mx+b)
I think it is y=mx+b would I be right on this?
My answer is you would substitute (0,b) into m and you would arrive at y=mx+b
Is this right?
