Answer:
Rahm: 0.8
Bain: 1.2
Step-by-step explanation:
For this, they ask for the rate of change or slope. To find slope you can use slope formula to get your slope/rate of change.
Steps for Rahm:
We can take points (10,8) and (20,16) and find the slope with the following formula: 

This is the rate of change for Rahm
Steps for Bain:
Take the points (5,6) and (11,13.2) and plug them into the Slope Formula:

Therefore, Bain hiked faster than Rahm for he had the higher rate of change compared to Rahm.
First multiply 2 to both sides to isolate q. Since 2 is being divided by q, multiplication (the opposite of division) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.
× 2 < 2 × 2
q < 4
For the graph will you have a empty or colored in circle?
If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.
If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.
Which direction will the ray go?
If the variable is LESS then the number then the arrow will go to the left of the circle.
If the variable is MORE then the number then the arrow will go to the right of the circle.
In this case your inequality is:
q < 4
aka q is less then four
This means that the graph will have an empty circle and the arrow will go to the left of 4. (look at image below)
Hope this helped!

Answer: d
(-5,3)(5,7)
Slope = change in y /change in x
M= 7-3/5-(-5)
M= 4/ 10
M=4÷2/5÷2
M=2/5
Your slope is 2/5 in fraction form or 0.4 in decimal form

mark me as brainliest if i’m right !
