The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −15 0 −10 1 −5 g(x) g(x) = 2x + 8 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)

Respuesta :

f(x) = -5x - 5. You can get this by using the slope formula and then point-slope form. 

1. The slope of f(x) is steeper as that of g(x), but it is also negative whereas g (x) is positive.

2. The y intercept of g(x) is much greater than that of f(x) because 8>-5
