Y = mx + n
m = Slope
To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1
y = 2x + 5
ma = 2
D: y = -1/2x + 5
mb = -1/2
ma x mb = -1
2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1
It's true.
Answer: D.
The two other points would be (13,1) and (13,13) because the square tile is 12 inches on each side.

Answer: Region C</h3>
=============================================================
Explanation:
Check out the screenshot below.
I formed a fourth column where we divide each population over its corresponding area. For example, region A will have a population density of roughly 1312/212 = 6.19 which means there are 6.19 zebras per square km.
The higher the population density, the more competition for resources. We see that region C has the highest density at about 26.24 zebras per square km. There are more zebras competing for food/water/shelter/etc in the same relative area compared to the other regions.
