Answer: ( 12 , 9 )
Step-by-step explanation:
The formula for finding the coordinate of points when a line is externally divided in a given ratio is given by :
x =
y =
From the question
= 2
= ?
x = 4
= -1
= ?
y = 1
p = 1
q = 4
substituting the values into the formula ,we have
x =
4 =
4 =
+ 8 = 20
= 12
Also
y =
1 =
- 4 = 5
= 9
Therefore , the end of the stencil is located at point ( 12 , 9 )
