Wat is the slope of the line that passes through the points 3,1) and (-2,5)
den301095 [7]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

m=\boxed{-\frac{4}{5}}

»»————- ★ ————-««  

Here’s why:  

  • We can use the slope formula to find the slope of the two points given.

⸻⸻⸻⸻

\boxed{\text{Recall that the slope formula is:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\(x_1,y_1), (x_2,y_2)-\text{Points}

⸻⸻⸻⸻

\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{5-1}{-2-3} \\\\\rightarrow m=\frac{4}{-5}\\\\\rightarrow \boxed{m= -\frac{4}{5}}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Sveta_85 [38]

Given:

Total forest area = 43,000

Old growth trees forest = 0.2%

To find:

The area of the old growth trees.

Solution:

We have,

Total forest area = 43,000

Old growth trees forest = 0.2%

Area of the old growth trees = 0.2% of 43,000

                                               = \dfrac{0.2}{100}\times 43000

                                               = 86

Therefore, the area of the old growth trees is 86 acres.
