Point Q^1


is the image of Q(0,6)

under the translation (X,Y---->(X+7,Y-5)

.
What are the coordinates of Q

?

1 answer

To find the coordinates of point \( Q \) after the translation defined by the rule \( (X, Y) \rightarrow (X + 7, Y - 5) \), we need to apply the inverse of this translation to find the original coordinates of \( Q \).

Given that \( Q^1 \) is the image of \( Q(0, 6) \) under this translation, we can express this as:

\[ Q^1 = (X + 7, Y - 5) = (0 + 7, 6 - 5) = (7, 1) \]

Now, to find the original coordinates of \( Q \) from \( Q^1(7, 1) \), we apply the inverse translation:

\[ (X, Y) \rightarrow (X - 7, Y + 5) \]

Applying this to \( Q^1(7, 1) \):

\[ Q = (7 - 7, 1 + 5) = (0, 6) \]

So, the coordinates of \( Q \) are \( (0, 6) \).
