5. What is the shape of the graph?
Linear
6. What happened to the resistance in the wire as you increased the wire length?
As the length of wire increased, the resistance in the wire also increased.
7. Does the graph verify your finding from question 6?
Yes
8. What type of mathematical function does this graph show? (linear, quadratic, inverse, power, etc.)
The graph shows a linear function
9. Using the graph, find the slope of the line; call the slope S. Be sure to show the slope calculations.
Slope = rise / run
Slope = (y2 - y1)/(x2-x1)
= (0.864 -0.069) / (0.1296 -0.0103)
= 6.65 ?/m
10. Using the value of the slope obtained in Item (9), calculate the quantity:
