Answer:

1/3

Andrew [12]

Answer:

y = -2/7x - 22/7

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

Point (-4, -2)

Point (3, -4)

Step 2: Find slope m

Substitute: $m=\frac{-4+2}{3+4}$
Add: $m=\frac{-2}{7}$

Step 3: Find y-intercept b

Define: y = -2/7x + b
Substitute: -4 = -2/7(3) + b
Multiply: -4 = -6/7 + b
Isolate b: -22/7 = b
Rewrite: b = -22/7

Step 4: Write linear equation

y = -2/7x - 22/7

Vhich of the following is a true statement about skew lines?

krok68 [10]

Answer:

A. Skew lines cannot lie in the same plane.

Step-by-step explanation:

(*Which)

Skew Line Definition (from Wikipedia): "In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel." -Wikipedia

"Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions." -Wikipedia

Skew lines cannot lie in the same plane so A is correct and C is incorrect.

B and D are incorrect because our friend Wikipedia just said it was incorrect.
