Answer:
Step-by-step explanation:
y = -x + 3
y + 1 = -(x + 1)
y + 1 = -x - 1
y = -x - 2
x + y + 2 = 0 is the solution
Answer:
see below
Step-by-step explanation:
We assume you want the graph of ...

A graphing calculator or spreadsheet is useful for this.
__
You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.
r at 0° = 8
r at 30° ≈ 7.05
r at 45° ≈ 6.19
r at 60° ≈ 5.33
r at 90° = 4
r at 120° = 3.2
r at 135° ≈ 2.96
r at 150° ≈ 2.79
r at 180° ≈ 2.67
$46 divided by 5 which equals $9.50
