Final answer:
The slope of the function is -4 and the y-intercept is 4.
Step-by-step explanation:
The slope-intercept form of a linear equation is given by y = mx + b, where m is the slope and b is the y-intercept. In the given function, f(x) = -4x + 4, the coefficient of x (-4) represents the slope and the constant term (4) represents the y-intercept.
Therefore, the slope of the function is -4 and the y-intercept is 4.
