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:

Pre-Alg

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 (-3, 14)

Point (-1, 16)

Step 2: Find slope m

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

Step 3: Find y-intercept b

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

Step 4: Write linear equation

y = 6x + 22

Inga [223]

None of the options give the same fees for a session of x hours.

Given,
x + 20/2 = 3x
when two tutoring services with different rate plans charge the same fees for a session of x hours.

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements.

x + 20/2 = 3x
x + 10 = 3x

A) x= 10
10 + 10 = 3*10
20 ≠ 30

B) x=4
4 + 10 = 3 * 4
14 ≠ 12

C) x= -14
-14 + 10 = 3 * -14
-4 ≠ 42

D) x=-17
- 17 + 10 = 3 * - 17
-7 ≠ -51

Here, none of the options give the same fees for a session of x hours.

Thus, none of the options give the same fees for a session of x hours.

In 432 BC, part of the Greek city Olynthus was divided into rectangular city blocks measuring 120 feet by 300 feet. To the neare

Dafna1 [17]

Answer:

323 feet

Step-by-step explanation:

This is basically the Pythagorean Theorem. If you have experience with this formula, you will know that it only works with right triangles. Why are we talking about a triangle when this problem speaks of rectangles? Well, this is because when a rectangle is split diagonally, it is now two separate triangles. The Pythagorean Theorem states that a^2 + b^2 = c^2. To begin, we will take the base and height of the triangle and either square root them or square them. In this case, you will need to square them. When this is done, you will have the numbers 90,000 and 14,400. What do we do with these? We will add them together now. Next, we will take the sum of these two numbers (104,400), and square root it. This leaves you with 323.109888, but, we need to round it to the nearest foot or, the nearest whole number. This will give us 323 feet as our final answer. Glad I was able to help! ;):)
