    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)

    Yes, given two points, do you know how to find the "slope" ?

    You may take any two points to find the slope, maybe simply take the last two points : (0, -1) and (1, 9)

    10 is the slope of f(x), we got that by using the slope formula. lets find the slope of g(x) also so that we can compare

    Yes, because PartA is asking you to find both the slopes and compare them `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)`

    Finding slope of g(x) is easy, we can simply eyeball it. Use below : slope of the line \(g(x) = \color{red}{m}x+b\) is \(\color{Red}{m}\)

    slope of the line \(g(x) = \color{red}{5}x+1\) is \(\color{Red}{?}\)

    Easy, slope of the line \(g(x) = \color{red}{5}x+1\) is \(\color{Red}{5}\) as i said you simply need to eyeball it

    so which function has greater slope, f(x) or g(x) ?

    we have worked both the slopes just now slope of f(x) = 10 slope of g(x) = 5

    you should say, the function f(x) has larger slope compared to the slope of g(x)
