I'm completely stuck on this, I need a full explanation and solution

Answer 1

A translation of triangle ABC can be represented by the following matrix equation where B has

the coordinates (a, b) and C' has the coordinates (c, d)

Adding the two matrices on the left simplifies the equation:

Therefore, each element is the same:

The horizontal translation is x; the vertical translation is y                    

Translations: Right (7 units), Up (5 units)             

               

Coordinates of B and C' are:       

B (-4, -5) C' (9, 4)
