Answer 1

Explanation:

Resistor 10 ohm: Slope of regression line (V/A)= 9.630 ohm; Y-intercept of regression line (V)= 0.01457 ohm

Resistor 51 ohm: Slope of regression line (V/A)= 46.61 ohm; Y-intercept of regression line (V)= 0.008761 ohm

Light bulb (first 3 pts): Slope of regression line (V/A)= 13.66 ohm; Y intercept of regression line (V)= -0.3315 ohm

Light bulb (last 10 pts): Slope of regression line (V/A)= 46.98 ohm; Y intercept of regression line (V)= -3.454ohm
