Question

What is the distance between the points (−7, −3) and (−7, −9) ?

A 12 units

B 10 units

C 6 units

D 4 units

Answer 1

• (-7,-3)
• (-7,-9)

Distance

`\\ \sf\longmapsto √((-7+7)^2+(-9+3)^2)`

`\\ \sf\longmapsto √((-6)^2)`

`\\ \sf\longmapsto √(36)`

`\\ \sf\longmapsto 6`

Answer 2

• C. 6 units

Explanation:

Since the points have same x- coordinate of -7, the distance is the difference in y - coordinates:

• d = -3 - (-9) = -3 + 9 = 6

Correct choice is C
