Answer:

m = 9

Step-by-step explanation:

The slope of a line can be found through rise-over-run: dividing the change in y-coordinate over the change in x-coordinate -- (y₁ - y₂) ÷ (x₁ - x₂)

That looks like this: (-2 - 7) ÷ (-7 + 6) --> subtracting negative = adding positive

Add: -9 ÷ -1

Divide: 9

Trava [24]

Answer:

Following are the solution to this question:

Step-by-step explanation:

For this set, the correlation coefficient is = -0.015.

It shows that financial variables have trust issues. Once a price rises, the other one is decreasing the value of -0,015 shows, that there are several fewer associations in the set of data among x and y and between y values. This interaction also can range between -1 to 1, to 0 being completely unrelated. But you'd never be sure, in this situation, 0.015 is very similar to 0.

It means that your prediction is nothing better than just a wild choice. Its odds of an estimated value being relatively close to the actual result are therefore much smaller as the points are it's hardly the best match.

Firlakuza [10]

Answer:

y=6x+7

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and can find the slope.  

Point slope:y-y_1=m(x-x_1)

We will substitute m=6 and x_1=-1\\y_1=1.

y-1=6 (x-(-1))

We can simplify and convert to slope intercept form.

y-1=6 (x-(-1))\\y-1=6(x+1)\\y-1=6x+6\\y=6x+6+1\\y=6x+7

<u>4x+8:</u>

9x+2-5x+6

2x+1+2x+7

<u>-4x-8</u>

-7x-10+3x+2

-7x-10+3x+2

<u>4x-8:</u>

-x+5+5x-13

-2x-7+6x-1

Step-by-step explanation:

We will have to solve each expression to see to which category it belongs

So,

1. 9x+2-5x+6

9x-5x+2+6\\=4x+8

2. -2x-7+6x-1

=-2x+6x-7-1\\= 4x-8

3. 2x+1+2x+7

= 2x+2x+1+7\\= 4x+8

4. -6x+2+2x-10

=-6x+2x+2-10\\= -4x-8

5. -x+5+5x-13

=-x+5x-13+5\\=4x-8

6. -7x-10+3x+2

=-7x+3x+2-10\\=-4x-8

Hence,

<u>4x+8:</u>

9x+2-5x+6

2x+1+2x+7

<u>-4x-8</u>

-7x-10+3x+2

-7x-10+3x+2

<u>4x-8:</u>

-x+5+5x-13

-2x-7+6x-1
