Question

Two functions are represented in different formats.

Answer 1

First let as solve the equation of the function 2:
solve the slope of the function
m = (y1 - y2) / (x1 - x2)
m = (65 - 85) / (0 - 1)
m = 20

then solve for the y intercept using one point ( 0, 65)
y = mx + b
65 = (20)0 + b
b = 65
so the equation is
y = 20x + 65

so the correct answer is Function 1 has a greater rate of change than function.  function 1 has 32 rate of change while function 2 is 20
