Hiya um so please help me

Question

1.) Identify the matrix transformation of ΔDEF, which has coordinates D(3, −2),E(4, 1), and F(7, 2), for a translation 1 unit left and 2 units up. Then identify the correct vertices of the image.

 

A.) 

 

B.) 

 

Answer 1

A is correct

subtract 1 from the x coordinates, if it is shifted 1 left. Immediately you see A is correct and B is wrong

a shift left means a lesser x, not greater. B adds when it should subtract
