Move Points on a Grid

When we shift points on a grid, their coordinates change because their positions have moved.

A horizontal shift will change the x-coordinate.

Shifting A 8 units to the right moves it from A(-5, -5) to B(3, -5).

We have added 8 to the x-coordinate.

Shifting B 8 units to the left moves it from B(3, -5) to A(-5, -5).

We have subtracted 8 from the x-coordinate.

A vertical shift will change the y-coordinate.

Shifting B 8 units up moves it from B(3, -5) to C(3, 3).

We have added 8 to the y-coordinate.

Shifting C 8 units down moves it from C(3, 3) to B(3, -5).

We have subtracted 8 from the y-coordinate.

Let's have a go at some questions now.
