Hellp? Between x = 0 and x = 1, which function has a greater average rate of change than y = 3x?

a, y = - 8x + 2

B) y = 5x + 2

C) y = 4-x

D) y = - 5x

In this case, you must remember that the average change rate in linear equations is given by the value of the slope of the line of each equation.

We have then that:

y = 3x

m = 3 (average rate of change)

Therefore the line sought is:

y = 5x + 2

m = 5 (greater average rate of change than 3)

answer:

The function that has a greater average rate of change than y = 3x is

B) y = 5x + 2
