Answer:
The distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Step-by-step explanation:
Given the points
Finding the distance between (-1, 1) and (2, -4) using the formula
substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)
units
or
units
Therefore, the distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
