[ Answer ]
[ Explanation ]
The Median Is The Number That Separates Top Half Of The Number Set From The Bottom
Ex: 1, 1, 2, 5, 6, 6, 9
Median - 5
Explanation: 5 is the number in the exact middle that is separating the bottom half of the number set (1, 1, 2) from the top half of the number set (6, 6, 9).
Ex: 1, 1, 2, 6, 6, 9
Median - 4
Explanation: 4 is the mean of 2 and 6. (Mean = Sum / Numbers you are adding up)
===========================
22, 37, 49, 15, 72
Order numbers from least to greatest:
15, 22, 37, 49, 72
37 is the mean because it is in the exact middle and separates 15 and 22 from 49 and 72.

Answer:
The Slope of Line 1 is ->
The Slope of Line 2 is ->
These two lines are - > Perpendicular
Step-by-step explanation:
To find the slope of line one, you follow these steps:
First Coordinate 10 -> x1, 5 -> y1
Second Coordinate -8 -> x2, 9 -> y2
Then insert the assigned values into this equation: ->
which equals
which simplifies to
Then do the same process to find the slop of line 2:
First Coord: 2 -> x1, -4 -> y1
Second Coord: 11 -> x2, -6 -> y2
Then insert the values into this equation: ->
which equals
.
We know the lines are perpendicular by:
a. Typing the equations of the lines into a graphing calculator and observing the graph
b. Looking at the slopes. By looking at the slopes, we see that the slope of line 1 is the reciprocal of line 2, and vice versa. Since reciprocal slopes indicate perpendicular lines, the lines 1 and 2 are perpendicular to each other.
