The question

Question: translate the point P(4, 4) left 1, down 6.

P = (4, 4)
= left 1, down 6

1 Draw the shape

Put the point on the grid.

2 Read the move

Left 1 means x gets 1 smaller: x − 1.

Left 1 → x − 1

Down 6 means y gets 6 smaller: y − 6.

Down 6 → y − 6

So every point (x, y) goes to (x − 1, y − 6).

(x, y) → (x − 1, y − 6)

3 Move each point

Start at P.

Go left 1.

Then go down 6.

We land on the new point.

We call the new point P prime.

The little mark means: the new P.

P is (4, 4).

Left 1: 4 minus 1 is 3.

Down 6: 4 minus 6 is −2.

So P' is (3, −2).

P(4, 4) → (4 − 1, 4 − 6) = P'(3, −2)

Careful!

Down makes y smaller.

So we take 6 away.

We do not add it.

Careful: not P'(4 − 1, 4 + 6) ✗

4 The new point

So the image is P'(3, −2).

P' = (3, −2)

5 Check

Let's check.

Draw an arrow from each point to its new point.

The arrow goes left 1, down 6.

Right!

P → P': left 1, down 6

Let's look back.

First: draw the shape.

Then: read the move.

Then: move each point.

Then: the new point.

Last: check.

Answer
P' = (3, −2)

Your turn

Try this one yourself, then check:

P(6, 2): left 2, down 3
Show the answer
P' = (4, −1)
