Translations are just shifts Translations are just shiftsup Translations are just shiftsupUp 6 Translations are just shiftsup, down Translations are just shiftsup, downDown 5 Translations are just shiftsup, down, left Translations are just shiftsup, down, leftLeft 3 Translations are just shiftsup, down, left, and right Translations are just shiftsup, down, left, and rightright 4 Sometimes translations can be written like this Sometimes translations can be written like this(x+3,y+2) Sometimes translations can be written like this(x+3,y+2)This means Sometimes translations can be written like this(x+3,y+2)This meansa right translation of 3 Sometimes translations can be written like this(x+3,y+2)This meansa right translation of 3 Sometimes translations can be written like this(x+3,y+2)This meansanda right translation of 3an up translation of 2 Sometimes translations can be written like this(x+3,y+2)This meansanda right translation of 3an up translation of 2 Moving the point 4 places to the right Moving the point 4 places to the right Moving the point 4 places to the rightis a plus 4 to the x value Moving the point 4 places to the rightis a plus 4 to the x value(x+4, y) Moving the point 4 places to the left Moving the point 4 places to the left Moving the point 4 places to the leftis a subtraction of 4 from x Moving the point 4 places to the leftis a subtraction of 4 from x(x-4, y) (x+3, y)Right 3?Left 3?(x-3, y) Moving the point 4 places up Moving the point 4 places upis an addition of 4 to the y Moving the point 4 places upis an addition of 4 to the y(x, y+4) Moving the point 4 places down Moving the point 4 places down Moving the point 4 places downis a subtraction of 4 from the y Moving the point 4 places downis a subtraction of 4 from the y(x, y-4) Check all that apply(x-5, y-12)RightUpDownLeft Check all that apply(x-3, y+1)Right 3Right 1Left 3Left 1Down 1Up 3Up 1Down 3 Check all that apply(x+8, y+4)Right 8Right 4Left 8Left 4Down 4Up 8Up 4Down 8 Which point is thePoint A translated:correct answer?(x-2, y+1)HGIFABEDC Right 2, Up 4Left 1, Up 4(x+2, y+4)?(x-1, y+4)?Match the translationRight 7, Down 3Left 3, Up 2(x-3, y+2)?(x+7, y-3)?Left 2, Down 1Left 7, Up 3(x-7, y+3)?(x-2, y-1)?

In order to turn a pointIt is helpful to use the "L" shape. In order to turn a pointIt is helpful to use the "L" shape. In order to turn a pointIt is helpful to use the "L" shape. In order to turn a pointIt is helpful to use the "L" shape. In order to turn a pointIt is helpful to use the "L" shape.or you could draw the "L" like this In order to turn a pointIt is helpful to use the "L" shape.or you could draw the "L" like this To rotate the point 90∘ clockwise, turn the 'L' To rotate the point 90∘ clockwise, turn the 'L' To rotate the point 90∘ clockwise, turn the 'L' To rotate the point 90∘ counter clockwise,turn the 'L' the other way To rotate the point 90∘ counter clockwise,turn the 'L' the other way To rotate the point 90∘ counter clockwise,turn the 'L' the other way turn the 'L' twiceTo rotate the point 180∘, turn the 'L' twiceTo rotate the point 180∘,once turn the 'L' twiceTo rotate the point 180∘,twice Point A rotated 180∘CBDA Point A rotated 90∘ clockwiseCBDA Point A rotated 90∘ counter clockwiseCBDA A dilation enlarges or reduces an object. A dilation enlarges or reduces an object.We can use the "L" method again. A dilation enlarges or reduces an object.We can use the "L" method again.
