Answer:
Q (-6.6), R (-6.0), S (0.0)
Step-by-step explanation:
In the exercise we are asked to find the original coordinates with the given transforms, which means that we must apply the inverse of the indicated transformations.
Original coordinates: Q "(6, -1), R" (0, -1) and S "(0, -7)
When turning 90 ° counterclockwise, since we want the opposite, the following change occurs (the axes and the sign are inverted):
Q '(1.6), R' (1.0), S '(7.0)
Now we have to move to the left by 7 units, because it is the opposite of the right, only on the x axis, 7 is subtracted
Q (-6.6), R (-6.0), S (0.0)
