PLEASE HELP PLEASE!!!
Alja [10]

Answer:

F; A translation of 6 up and 4 left and a reflection across the x-axis

Step-by-step explanation:

Here, we want to perform the translation that would move S to S’

to do this, we can have a subtraction

For 1 to move to -3 on the x-axis;

it means there is a leftward shift of upto 4 units

For -8 to turn to 2;

this is positive; there is a vertical upward translation of upto 10 units on the y-axis

This option is not directly available; thus we have to factor the reflection

if we reflect on the x-axis, the y-axis value becomes negated; if we reflect on the y-axis, the x-value becomes negated

The correct answer is thus;

A translation of 6 up and 4 left, followed by a reflection across the x-axis
