Question 1026470: Function 1: y = 4x + 5
Function 2: The line passing through the points (1, 6) and (3, 10).
Which of these functions has the greater rate of change? And why?

Both are linear functions. For linear functions the rate of change is represented by its slope.
The slope of the first function is 4. (The equation is written in slope-intercept form.)
The slope of the second function is %2810-6%29%2F%283-1%29+=+4%2F2+=+2.
The answer is clear now.
