Chapter 1, Section 3.1

A linear function is given.

(a) Determine the slope and y-intercept of each function.
(b) Use the slope and y-intercept to graph the linear function.
(c) Determine the average rate of change of each function.
(d) Determine whether the linear function is increasing, decreasing, or constant.

14. g(x) = 5x - 4

16. p(x) = - x + 6

18. h(x) = [tex]\frac{-2}{3}[/tex]x + 4

20. G(x) = - 2

[Eigenvalue]

14a. Slope: 5, y-intercept (0,4)
15a. Slope: -1, y-intercept (0,6)

16a. Slope: [tex]\frac{-2}{3}[/tex], y-intercept (0,4)
17a. Slope: 0, y-intercept (0,-2)

14a. Slope: 5, y-intercept (0,4)
15a. Slope: -1, y-intercept (0,6)

16a. Slope: [tex]\frac{-2}{3}[/tex], y-intercept (0,4)
17a. Slope: 0, y-intercept (0,-2)

Cool. Simple and straightforward.
