HELP URGENT ASAP PLEASEEEEE

What is the average rate of change? How do you calculate it? What can you tell about the average rate of change for linear functions? Compare the slopes of horizontal and vertical lines.

Answer 1

Average rate of change it a slope. slope=y2-y1 divided by x2-x1.
on a linear function the average rate of change it rise over run(find two points, count then divide it)
horizontal line has a slope and its 0
vertical line has no slope

Answer 2

Hope this helps!

When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h)2 Therefore, the slope of the secant line between any two points on this function is 2x + h.
