Comparing Linear Functions and Their Characteristics

Why is it important to understand the concept of slope before proceeding with comparing linear functions?

• Because it helps in understanding the y-intercept.

• Because it is necessary for calculating the rate of change.

• Because it helps in solving polynomial equations.

• Because it is a prerequisite for understanding quadratic functions.
