What we have been given here are two points.

f(3) = -4 is the same as (3, -4)

f(2) = 6 is the same as (2, 6)

We can then use these two points to find the equation of a line.

Step 1: Find the slope

Slope Formula: (y2 - y1) / (x2 - x1)

Slope = (6 - - 4) / (2 - 3) = (10) / (-1) = -10

Step 2: Find the y-intercept

To find the y-intercept, we'll take our slope and one of our points and plug them into slope-intercept form, then solve for b.

Slope-Intercept Form: y = mx + b

Point = (2, 6)

6 = 2(-10) + b

6 = -20 + b

b = 26

Step 3: Create the equation of the line

Now that we have the slope and y-intercept, all that's left to do is plug both of those values into slope-intercept form.

y = -10x + 26

Answer: y = -10x + 26

Hope this helps!

Answer:

1. 4/7 = 16/28

Check:

(4/7)(4/4) = 16/28 = 16/28

2. 40/15 = 8/3

Check:

(40/15)/(5/5) = 8/3

3. 15/6 = 5/2

Check:

(15/6)/(3/3) = 5/2

4. 8/11 = 56/77

Check:

(8/11)(7/7) = 56/77

5. 9/2 = 63/14

Check:

(9/2)(7/7) = 63/14

Marquis used the steps below to find the solution to the inequality Negative 5. 6 greater-than-or-equal-to x 3. 6. Step 1 Subtra

NISA [10]

Marquis solutions are;

The value of x is less than or equal to -9.2.
Negative 9.2 is greater than or equal to x.
The closed circle is at -9.6 that is everything to the left of the circle is shaded.

<h3>What is inequality?</h3>

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.

Marquis used the steps below to find the solution to the inequality Negative 5.6 greater than or equal to x + 3.6 that can be written as

$\rm -5.6 \geq x + 3.6$

A. Then the value of x will be

- 5.6 ≥ x + 3.6

-5.6 - 3.6 ≥ x

-9.2 ≥ x

B. Negative 9.2 is greater than or equal to x.

C. The number line is shown. The closed circle is at -9.6 that is everything to the left of the circle is shaded.

Edwin writes an absolute value equation to determine the values that are 0.3 units from 3.9.

Fittoniya [83]

The absolute value equation written by Edwin according to his intention in the task content is; |x -3.9| = 0.3 and The values that are 0.3unuts from 3.9 are; 4.2 and 3.6.

<h3>What absolute value equation can be written by Edwin to find the numbers which are 0.3 units away from 3.9 on the number line?</h3>

Since the numbers in discuss are required to be 0.3 units from 3.9, it follows that one number is greater while the other is less than 3.9 and hence the required absolute value equation is;

|x -3.9| = 0.3. which can be solved as;

x-3.9 = 0.3; x =4.2.

x -3.9 = -0.3; x = 3.6.

Anni [7]

Q. When describing average home sale prices, explain why the median might be more appropriate measure of center than the mean. A. When looking for the average, we usually don't get the approximate price that we are looking for. What we are instead receiving is the rounded figure from the various other prices, rather than finding the "center" price. Whereas, in finding the median, we get the center price (since using median we find the number that is in the approximate middle). That will get us the "core" price for the selection of the homes instead of getting the rounded figure in average. Q. Are all home prices about the same in a city? A. There are no approximate answer for this. This topic is similar to when you are deciding where to start your next business. You need to look at the environment, education, communication etc., before deciding to buy a house. From my point, I would say that not all the houses in the city have the same price. You need to look most at the built-in architectural designs to have a higher price. However, if you look for a some-what luxury house, then you will have more of a lower price.
