Which is the slope of the line that passes through the points (3,5) and (8,7)?

Hatshy [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

$m=\boxed{\frac{2}{5}}$

»»————-　★　————-««

Here’s why:

The formula for the slope of two given lines given is 'rise over run'.

⸻⸻⸻⸻

$\boxed{\text{Slope Formula:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\\rightarrow (x_1,y_1),(x_2,x_1) - \text{Two Points Given}$

⸻⸻⸻⸻

We are given the points (3,5) and (8,7).

⸻⸻⸻⸻

$\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{7-5}{8-3}\\\\\rightarrow \boxed{m=\frac{2}{5}}$

⸻⸻⸻⸻

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

Answer:

The fuel economy is 36 miles per gallon. For each mile 1/36 gallon will be used.

Initial volume is 13,2 gallons and x is the number of miles.

Our equation is:

y = 13.2 - 1/36x

y = -1/36x + 13.2
