Resistance of a Wire

Making the graph in Gooooogle Sheets:

You will need to print the graph from a PC in the back of my room

Make sure you specify the boundaries so the graph has a plot frame and has the origin 0,0 on it!!  (X axis goes to zero)

Make sure to add gridlines to help you read the graph!!

Drawing the maximum and minimum slope lines:

Do this by hand with a clear ruler on the printout of the graph.

Calculating the Maximum and Minimum slopes:

Expressing the resistance of the wire as a value plus or minus an uncertainty:
