We need to find the slope

Colt1911 [192]

Hello!

Step-by-step explanation:

Slope: $\frac{Y^2-Y^1}{X^2-X^1}=\frac{rise}{run}$

$\frac{9-3=6}{2-(-1)=2+1=3}=\frac{6}{3}=2$

Therefore, the slope is 2.

Answer is 2.

Hope this helps!

Thank you!

I'm confused on what to do. Please I need the awnser ASAP

Ganezh [65]

The answer is in the base speed. They have the same base speed for every quarter hour, 10 miles per quarter hour! And since 1/2 is equivalent to 2/4, then it has the speed rate of 20 miles in a half hour.

If you need anything else, comment below please!
