Question

PLEASE HELP ME!!

1) determine the coordinate of B

2) Determine the coordinate of C

3) describe the transformation from ABC TO A’ B’ C’

4) write an algebraic rule for the transformation from ABC to A’ B’ C’

5) if P is reflected about the line y = x, determine the new coordinate

6) write an algebraic rule for the reflection about the line y = x for any coordinate

Answer 1

1. The coordinate of B is (6, 2)

2. The coordinate of C is (1, 2)

3. The transformation from from ABC to A’ B’ C’ is translation 6 units left, and 7 units down.

4. The transformation from from ABC to A’ B’ C’ is (x - 6, y - 7)

5. The new coordinates of P will be (2, -4)

How to find the coordinates

The coordinates of B is sought using points A and C. B and A share same x coordinate while B and C share same y coordinate. This will result to (6, 2)

The coordinate is in the diagram as (1, 2).

The transformation from from ABC to A’ B’ C’ is translation

• 6 units left (In x axis), and

• 7 units down. (In y axis)

This translation will result to the rule (x - 6, y - 7)

The new coordinates of P is gotten by interchanging the coordinates> This process will result to (2, -4)
