The slope of the line will allow us to determine the resistance of the wire so option (D) will be correct.
<h3>What is a linear function?</h3>
A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
Resistance of a wire is given by
R = V/I
The slope of a linear function is nothing by
Slope = y/x
So,
The slope of the given diagram
Slope = V/I
So,
R = Slope
Hence to determine the resistance we need to determine the slope of the graph.
