Question

The table below represents a linear function f(x) and the equation represents a function g(x):


x
f(x)
-1
-9
0
-1
1
7
g(x)

g(x) = 3x - 2


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

lemme fix the table
x -1 0 1
f(x) -9 -1 7

Answer 2

Okay, you would like to find the slope of which equation first?

Answer 3

anyone is fine

Answer 4

i guess x

Answer 5

Well there're two functions f(x) and g(x) so x means?

Answer 6

i dont know

Answer 7

Okay... Let's do f(x) first

Answer 8

alright

Answer 9

Pick two points, the slope is rise/run.

Answer 10

That means y-distance over x-distance

Answer 11

Or \(\dfrac{y_2-y_1}{x_2-x_1}\)

Answer 12

-1 and -9?

Answer 13

Okay you can use the points (0,-1) and (-1,-9)

Answer 14

ok so
