Question

What is the distance between the points (2, -5) and (-5, -5) on a coordinate plane?

Answer 1

The distance between the points (2, -5) and (-5, -5) on a coordinate plane is 7 units.

Explanation:

Distance Formula:
`d=\sqrt{(x_(2)-x_(1))^(2)+(y_(2)-y_(1))^(2)}`

`d=\sqrt{(-5-2)^(2)+(-5-(-5))^(2)}\\d=\sqrt{(-7)^(2)+(0)^(2)}\\d=√(49)\\d=7`

Answer 2

7

Explanation:

Both points are on the horizontal line y = -5. The distance between them is the difference of their x-coordinates:

2 -(-5) = 2+5 = 7

The distance between the points is 7 units.
