Basically, you could set these proportions up in two ways. You could set it up as 5/35=10/x, or you could set it up as 5/10=35/x. Either way, you will get the same answer. After setting one of them up, cross multiply. You should come out with 5x=350. Divide 350/5. Here you should get the answer of 70. 70 should be the length of LN

A line passes through the points (-3, 14) and (-1, 16). What is its equation in slope-intercept form?

timurjin [86]

Answer:

y = 6x + 22

General Formulas and Concepts:

<u>Pre-Alg</u>

Order of Operations: BPEMDAS

<u>Algebra I</u>

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:

<u>Step 1: Define</u>

Point (-3, 14)

Point (-1, 16)

<u>Step 2: Find slope </u><em><u>m</u></em>

Substitute: $m=\frac{16-14}{-1+3}$
Subtract/Add: $m=\frac{12}{2}$
Divide: $m=6$

<u>Step 3: Find y-intercept </u><em><u>b</u></em>

Define: y = 6x + b
Substitute: 16 = 6(-1) + b
Multiply: 16 = -6 + b
Isolate <em>b</em>: 22 = b
Rewrite: b = 22

<u>Step 4: Write linear equation</u>

y = 6x + 22

Which of the following is not an inertial reference frame? Which of the following is not an inertial reference frame?

hammer [34]

An inertial reference frame is a frame of reference in which a body remains at rest OR moves with a constant LINEAR velocity. Answer choices A, C, and D are moving linearly at a constant rate and are all inertial frames of reference. Answer choice E is motionless, and is therefor an inertial frame of reference. Answer choice B is rotating at a constant rate. Rotation is not an inertial frame of reference.
Therefor, the answer is B.
