1/2
Step-by-step explanation:
When you have two points you need to use the slope formula:

x1 and y1 is the first point and x2 and y2 is the second point, remember that the first number is X and the other is Y so...

1/2 is the slope of the points
I don't know what the "act it out" strategy is but I will try to help based on my knowledge.
Try this: Write down the numbers 1-4. Then make number combinations with 3 of those 4 numbers. See how many you can make with out repeating a combination. Even it is in a different order. How ever many combinations you can mane is your answer.
This is how I would do it.
Let me know if this helps or not.
Good Luck
5 questions times 4 choices = 20 possibilities. However you should never leave anything blank because even a guess can possibly be the right answer
