Which of the following describes the movement of a figure that is translated according to the rule below? (x,y) (x-7,y+1) Questi
Murrr4er [49]

Answer:

Taking (x,y) into account, here's the math.

Step-by-step explanation:

We know x is the horizontal line, so it will be moving to the left or right, while y is the vertical, meaning it will move up or down.

If we do x-7, that means we're moving towards the left 7 times, or in other words, closer to the negative side.

If y is +1, then that means we'll be moving up 1, closer to the positives.

So, your answer would be,

<u>Left 7 units and up 1 unit.</u>
