Answer:
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
We have the two points (-1, 7) and (-8, -3).
Let (-1, 7) be (x₁, y₁) and let (-8, -3) be (x₂, y₂). Substitute:
Evaluate:

Square:
Add:
This cannot be simplified. Hence, the distance between (-1, 7) and (-8, -3) is √(149) or approximately 12.21 units.
