Answer:
√29 units
Explanation:
Find the distance between (-1,4) and (1,-1).
We'll use the Pythagorean Theorem:
The horizontal distance between the two points is 1 - (-1), or 2, and the vertical distance is 4 - (-1), or 5.
Thus, the distance squared is 2^2 + 5^2, or 29, and the distance between the two points is therefore
d = √29 units
