Answer:
5
Explanation:
Draw straight lines from the origin to the two points.
This creates a right triangle.
The distance from (0, 0) to (0,-3) is
a = 0 – (-3)
a = 0 + 3
a = 3
The distance from (0, 0) to (4, 0) is
b = 4 – 0
b = 4
According to Pythagoras,
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²
c = 5
The distance between (-4,0) and (0,-3) is 5.
