How can you interpret the y-intercept of a linear function?

• The y-intercept represents the average rate of change of the linear function.

• The y-intercept represents the slope of the linear function.

• The y-intercept represents the value of y when x is equal to zero.

• The y-intercept represents the value of x when y is equal to zero.
