9. Find the area of a circle having a circumference of 382. Round to the nearest tenth. Use 3.14 for 1. a. 1133.5 units b. 1078.6

1. belindajolete says:

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

Divide: 9

$\displaystyle =9$

Step-by-step explanation:

The slope formula is

$\displaystyle \frac{y_2-y_1}{x_2-x_1}$

$\displaystyle y_2=7\\\displaystyle y_1=(-2)\\\displaystyle x_2=(-6)\\\displaystyle x_1=(-7)$

$\frac{7-(-2)}{(-6)-(-7)}=\frac{9}{1}=9$

Therefore, the slope is 9, and the correct answer is 9.

Hope this helps!

4. mcalepcrager says:

slope=9

Step-by-step explanation:

m=∆y/∆x

=(7+2)/(-6+7)

=9/1

=9

5. tbair5417 says:

-2-7=-9
-7-6=-13=9/13

6. marelinatalia2000 says:

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =7\\y_{1} =-2\\x_{2} =-6\\x_{1} =-7$

^^^Plug these numbers into the formula for slope...

$\frac{7-(-2)}{-6 - (-7)}$

$\frac{9}{1}$

OR

9

Hope this helped!

9

Step-by-step explanation:

Slope is rise over run or change y/change x.

7 - -2 = 9

-6 - -7 = 1

Slope = 9/1 or 9

I AM ALWAYS HAPPY TO HELP 🙂

shown the slope and equation

$What is the slope of the line through (-7, -2) and (-6, 7)?$

9. BaileyElizabethRay says:

Well the formula is Y2-Y1/X2-X1
So you do 7-(-2)/(-6)-(-7). Giving you 9/1 meaning 9 is most definitely your answer.I hope this helped.

$\bf (\stackrel{x_1}{-7}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{-6}~,~\stackrel{y_2}{7}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{7-(-2)}{-6-(-7)}\implies \cfrac{7+2}{-6+7}\implies \cfrac{9}{1}\implies 9$

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
