Question

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

Answer 1

• (-7,-3)
• (-7,-9)

Distance

$\\ \sf\longmapsto \sqrt{(-7+7)^2+(-9+3)^2}$

$\\ \sf\longmapsto \sqrt{(-6)^2}$

$\\ \sf\longmapsto \sqrt{36}$

$\\ \sf\longmapsto 6$

Answer 2

Answer:

• C. 6 units

Step-by-step 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
