Question

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 y-intercept? Justify your answer. (4 points)

Answer 1

@peachesncream8 @TheSmartOne @pooja195 could one of you please help me

Answer 2

You need to use the slope and the point slope formula to find the line for f(x).

Answer 3

er actually you have the y-intercept so just the slope and slope intercept equation.

Answer 4

@Evoker ik but im just still so confused

Answer 5

Ok well for the slope, its (y2-y1)/(x2-x1) or for your case (-1--5)/(0--1) which yield 4/1 or 4 for your slope and your y-intercept is when x=0 or -1. So your line is y=4x-1

Answer 6

* or f(x)=4x-1, finally as they point out they have the same slope, but g(x) has a greater y-intercept

Answer 7

@Evoker ok

Answer 8

@skullpatrol could you help me understand
