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.
