SOLUTION
For question 4
We want to locate the opposite of point K,
To obtain the opposite of point k, we count from the point zero(0), backwards on the negative 8 times,
Consider the image below.
Hence the opposite of point K which is point L is
For question 5
Since Point zero is the middle school, then
L in relation to point zero: Point L is west of the middle school with a length is 2/3 to the middle school.
Hence
The L in relation to K: Point L is in the west of K with a length of 4/3 from K.
