Question

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? A) Function 1, because the slope is 5 and the slope of function 2 is 4. B) Function 1, because the slope is 4 and the slope of function 2 is 2. C) Function 2, because the slope is 7 and the slope of function 1 is 5. D) Function 2, because the slope is 5 and the slope of function 1 is 4.

Answer 1

function 1 : y = 4x + 5....slope is 4

function 2 : (1,6)(3,10)
slope = (10 - 6) / (3 - 1) = 4/2 = 2....slope is 2

B. function 1, because the slope is 4 and the slope of function 2 is 2.
