Required

% decrease

% decrease=350/850*100

% decrease= 0.41*100

What are the coordinates of the imageof point A (2, -7) under the transalition (x,y) (x- 3, y 5)

jenyasd209 [6]

Answer:

The coordinates of the image of point A (2, -7) are A'(-1,-2).

Step-by-step explanation:

Note: The sign is missing between y and 5 in the rule of transitional.

Consider the rule of translation is

$(x,y)\Rightarrow (x-3,y+5)$

We need to find the image of point A (2, -7).

Substitute x=2 and y=-7 in the above rule.

$A(2,-7)\Rightarrow A'(2-3,-7+5)$

$A(2,-7)\Rightarrow A'(-1,-2)$

Therefore, the coordinates of the image of point A (2, -7) are A'(-1,-2).
