Question

What is the distance between the points (15, 3) and (15, -9) in the xy-plane?

24 units


6 units

7.5 units

12 units

Answer 1

Lets draw a number line here

Answer 2

waaaaaaaaaaait

Answer 3

Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
does this help ??

Answer 4

what this is middle school

Answer 5

lets make it more simple,
when the x co-ordinates are same,

the distance is the difference between y co-ordinates.

d = 3-(-9) = ... ?
