Fan for answer!
The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
−1 −5
0 −1
1 3
g(x)
g(x) = 4x + 3
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 yintercept? Justify your answer. (4 points)

Best ResponseYou've already chosen the best response.0yes take 2 of the points and plug em into the formula \[m=\frac{ y _{2}  y _{1} }{ x _{2}  x _{1} }\]
