How to determine the figure and its image after the translation
From the question, we have the following parameters that can be used in our computation:
l(0,-1), m(1-2) and n(-2,1)
The translation is given as
right 5 units
Mathematically, this is represented as
(x, y) = (x + 5, y)
Using the above as a guide, we have the following:
l'(0 + 5, -1), m'(1 + 5, -2) and n'(-2 + 5,1)
Evaluate
l'(5, -1), m'(6, -2) and n'(3,1)
Hence, the points after the translation are l'(5, -1), m'(6, -2) and n'(3,1)
