Question 1
Use matrix multiplication to move a triangle with vertices A(10,20) B(30,80) and C(70,0) to the right 50 pixels and down 30 pixels. What is the location of the new triangle?
◦
A'(60,50) B'(80,110) C'(80,-30)
◦
A'(-40,50) B'(-20,110) C'(20,-30)
◦
A'(60,-10) B'(80,50) C'(120,-30)
◦
A'(-40,-10) B'(-20,50) C'(-20,-30)
