Find the point of N on WZ that is 1/3 of the distance from W to Z
First, we have to find the distance between W and Z
W is on -5
Z is on 4
As we can see in the number line the distance between the 2 points is 9:
l-5-4l = l-9l = 9
Now, point N is 1/3 of the distance from W to Z.
Simply multiply the distance (9) by 1/3.
9 x (1/3) = 3
So, N is 3 units from -5
In the number line:
Point N is at -2 in the number line
