Answer:
The rate of change of a linear function is its slope, which is the coefficient of the x-term in the equation.
Item I: y = 0.25x + 2
The slope of this line is 0.25.
Item II: y = 2
This is a horizontal line with zero slope, so it has a rate of change of 0.
The slope of Item I is greater than the slope of Item II, therefore option C is correct: "The rate of change of item I is greater than the rate of change of item II".
