g(x)

g(x) = 5x + 1



Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

Answer 1

slope for f(x):

Slope for g(x)

y = mx + b

y = 5x + 1

m = 5

The slope for f(x) is twice the slope of g(x).
