Hey! Your rational number would be 
Answer:
The answer is 15 units.
Step-by-step explanation:
If you count the number of units from point A up to the same Y coordinate as point B, the amount of units is 9.
Then, the number of units from that point over to point B is 12 units.
Using this information, you can use the Pythagorean theorem to find that 9 squared is 81, 12 squared is 144, add 144 and 81 to get 225, and then you can find the square root of 225 which equals the answer of 15 units.
Answer: -4
The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.
Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.
rise/run
4/run
Left and right, the difference is only one unit.
4/run
4/1
4
This graph is also negative, so let’s add that in.
-4
This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.
