Question

What is the distance between the points located at (−7, −18) and (−7, 25)?

7 units
43 units
−43 units
−7 units

Answer 1

43 units

Explanation:

The distance between the two given points can be found using the formula for the distance between two points in a coordinate plane,

which is d = √((x₂ - x₁)² + (y₂ - y₁)²). In this case, the x-coordinates of both points are the same (-7), so we only need to calculate the difference between their y-coordinates: d = √((0)² + (25 - (-18))²) = √(43²) = 43 units. Therefore, the distance between the two points located at (-7, -18) and (-7, 25) is 43 units

Answer 2

43

Explanation:

The distance formula is

`\sqrt{{(x2 - x1)}^(2) + (y2 - y1)^(2) }`

So

`\sqrt{(25 + 18) ^(2) + ( - 7 + 7)^(2) } \\ = \sqrt{ {43}^(2) + 0 {}^(2) } = 43`
