8. For each function, find ordered pairs for x = -2, x = 5,2x=and x=0.75. Create tables of values.31a. y=9 - 4xb. y =х

Alenkinab [10]

We need to check the ordered pairs for x = -2, x=5, x= 2/3 and x = 0.75.

1. For the first function: y = 9-4x

x=-2

$\begin{gathered} y=9-4\cdot(-2) \\ y=9+8 \\ y=17 \end{gathered}$

The ordered pair is (-2,17).

x = 5

$\begin{gathered} y=\text{ 9-4}\cdot(5) \\ y=9-20 \\ y=-11 \end{gathered}$

The ordered pair is (5,-11).

x = 2/3

$\begin{gathered} y=9-4\cdot(\frac{2}{3}) \\ y=9-\frac{8}{3} \\ y=\frac{27-8}{3} \\ y=\frac{19}{3} \end{gathered}$

The ordered pair is (2/3, 19/3)

x = 0.75

$\begin{gathered} y=9-4\cdot(0.75) \\ y=9-3=6 \end{gathered}$
