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 top 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)

A)

let's get the slope for f(x)... we can use any two pair from those 3 points, so hmm let's use the first and last then



now, what's the slope of g(x)? well, g(x) is in slope-intercept form



so the slope of g(x) is 2 then

b)

the y-intercept, as in before the case of the plane, is when x = 0, let's take a peek at f(x), when is x = 0?    

and the y-intercept for g(x) is pretty obvious, check part a)

well, I'd like to point out, the y-intercept of f(x) is -1, and for g(x) is -7

ok...which one is greater, well, you know, on the negative side, for negative values, greater values are the ones closer to  0, so... -1 is indeed greater than -7, because -1 is closer to 0.

Not sure what the question is?
