Question

Find the distance between (-3,5) and (-9,5).

Answer 1

Answer:

6 units

Step-by-step explanation:

Distance between 2 points

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

Thus, distance between (-3, 5) and (-9, 5)

$= \sqrt{( - 3 - ( - 9))^{2} + (5 - 5)^{2} } \\ = \sqrt{( - 3 + 9)^{2} } \\ = \sqrt{6 ^{2} } \\ = 6$

Alternatively, notice that this line is a horizontal line as both points have the same y-coordinate of 5.

Thus, distance between the 2 points

= -3 -(-9)

= -3 +9

= 6 units
