ther is a way to do a linear regression imposing b=0? cause I need to have a linear regression function in the form y=(constant)*x with no b.

Good evening. When I tried to "show linear" it appears a message that saids: "domain error. An argument must be in a specified domain". How can I fix this problem?

My calculator keeps saying sintaxe error and saying that I have 2 or more arguments with dimensions that don't coexist. But that's not the case, everything is as it should be. What's going on??
