okay so I am quoting this, " the filament resistance increases as the bulb gets hotter.".. I have found the resistance using the slope formula. when it was cool i calculated 36.25 ohms
when is was hot i got 25 ohms. my calculations seem wrong unless....the smaller number means more resistance.

If you figure out what you did wrong, don't hide it, document it. Experimental science is full of mistakes. The winners learn from their mistakes. If you can't find anything you did wrong, be sure you have careful records of what you did. You'd be surprised how many significant discoveries started like this.

The resistance in most materials increases as a function of temperature. So, you have made an error somewhere in your measurements or calculations. Filament resistance increases as the filament heats, that is the number gets larger.

You have some mistake in your calculations. The more the resistance, the higher the number of ohms.

In order to get the correct values You need to use "OHMS" Law
I'd end up writing a novel explaining it but you can find it easily on the web.
