Answer: 5
The Distance between the coordinates of two points is measured by distance formula.
Step-by-step explanation:
The Distance between the coordinates of two points P(x1,y1) and Q(x2,y2) is measured by
Distance PQ= (x2-x1)²+(y2-y1)²
So, the distance between (-1,4 ) and (2,0) can be calculated by
Distance= (2-(-1))²+(0-4)²
= (3)²+(-4)²
=9+16 =
25 as
25 = 5
Distance = 5
So the distance between the two coordinates is 5.
Answer:
A
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = D(- 4, - 3) and (x₂, y₂ ) = E(- 5, 3)
d =

= ≈ 6.1 → A
