Answer:
The translation vector is (4, 4).
Vectorially speaking, a translation between two distinct point on cartesian plane is described by the following formula:
P'(x,y) = P(x,y) + T(x,y)P
′
(x,y)=P(x,y)+T(x,y) (1)
Where:
P(x,y)P(x,y) - Original point.
P'(x,y)P
′
(x,y) - Translated point.
T(x,y)T(x,y) - Translation vector.
If we know that P(x,y) = (-3, 1)P(x,y)=(−3,1) and P'(x,y) = (1,5)P
′
(x,y)=(1,5) , then the translation vector is:
T(x,y) = P'(x,y) - P(x,y)T(x,y)=P
′
(x,y)−P(x,y)
T(x,y) = (1,5) - (-3, 1)T(x,y)=(1,5)−(−3,1)
T(x,y) = (4,4)T(x,y)=(4,4)
The translation vector is (4, 4).
