Final answer:
The slope of the function f(x) = (4/5)x - 3 is 4/5 and the y-intercept is -3.
Step-by-step explanation:
The equation given is f(x) = (4/5)x - 3, which is in slope-intercept form, y = mx + b, where m represents the slope and b represents the y-intercept. The slope of the given function f(x) is 4/5, meaning for every increase of 1 on the horizontal axis, there is a rise of 4/5 on the vertical axis. The y-intercept is the point where the line intersects the y-axis, which is at -3 for the given equation.
