Question

Which point is the coordinate of the image of A under the transformation (0,-1 1,0)?

Answer 1

(x + 1, y + 1)

Explanation:

Translation of x-coordinate :

• New - Previous
• 1 - 0
• +1
• Rule for x : (x + 1)

Translation of y-coordinate :

• New - Previous
• 0 - (-1)
• 0 + 1
• Rule for y: (y + 1)

Hence, the points which describes the change :

• (x + 1, y + 1)

Answer 2

Old coordinate (0,-1)

New coordinate (1,0)

The translation is

• (x+1,y+1)

Verification

• (0+1,-1+1)=(1,0)

Image of (0,-1) is (0,1)

Image of (1,0) is (-1,0)
