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.**
