To complete the solution of - x - 8y = -1, we first need to substitute x for -15.
As so:

-(-15) - 8y = -1
15 - 8y = -1

Next, we can subtract 15 from each side to get:

15 - 15 - 8y = -1 - 15
- 8y = -16

Now, we can divide by -8 on each side to get the y by itself:

-8y / -8 = -16 / -8
y = -16 / -8
y = 2

There we go! y = 2 when x = -15! Hope I could help you out! Have a good one.

What is the equation of the function shown in the graph provided? y= _ x + _

Mkey [24]

Answer:

y = -3x - 6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Find points from graph.

x-intercept (-2, 0)

y-intercept (0, -6)

Step 2: Find slope m

Substitute: $m=\frac{-6-0}{0+2}$
Subtract/Add: $m=\frac{-6}{2}$
Divide: $m=-3$

Step 3: Redefine

Slope m = -3

y-intercept b = -6

Step 4: Write linear equation

Slope-Intercept Form: y = -3x - 6
