for f(x), using (0,-1) and (1,3), the slope
= (3+1)/(1-0) = 4
and the slope of g(x) = 2x - 7 is obviously 2, so .....
(write your sentence
as to part B, isn't (0,-1) your point on the y-axis ?
and isn't the y-intercept for g(x) = 2x - 7 equal to -7 ????
so ....
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) = 2x − 7
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).
Part B: Which function has a greater y-intercept? Justify your answer.
