Question

Two functions are represented in different ways.

Answer 1

For readability, please present tables in line by line format:

Function 2:
x   y
0 65
1 85
2 105
3 125

Find the slope of this line by choosing any 2 coordinate pairs:
       125-105
m = ------------ = 20
           3 - 2

The y-intercept of this line is easily found, since we see that at x=0, y=65.
The equation of this line is thust y = 20x + 65.

Compare this to the other:           y = 32x + 45

y = 32x + 45 has a greater rate of change than does y = 20x + 65.

Which equation has the larger y-intercept?

Choose your answer(s).  I believe that more than one is correct.
