GEOM CH 9 TRANSFORMATIONS

The image of the point A( 0 , 9 ) under a translation is A'( 7 , 4 )

Find the coordinates of the image of the point B( 8 , 0 ) under the same translation.

• ( 8 , 9 )

• ( 15 , 4 )

• ( 15 , -5 )

• ( 7 , 13 )

The translation ( x + 7 , y - 8 ) means to translate...

• 7 right 8 up

• 7 left 8 down

• 7 right 8 down

• 7 up 8 left

• 7 up 8 down

Translate ( -5 , 7 ) 4 units left and 6 units down

• ( -1 , 13 )

• ( -1 , -9 )

• ( -9 , 13 )

• ( -9 , 1 )

If A is translated 5 units right and 4 units up

the result is A' ( -3 , 0 )

what was the ordered pair for A?

• ( 2 , 4 )

• ( -8 , -4 )

• ( 2 , -4 )

• ( -8 , 4 )

If ( 5 , -6 ) is reflected over the x-axis the resulting ordered pair will be...

(you can use desmos)

• ( 5 , 6 )

• ( -5 , -6 )

• ( -6 , 5 )

• ( 6 , -5 )

If ( 2 , -9 ) is reflected over the line y = x

the resulting ordered pair will be...

(you can use desmos)

• ( 2 , 9 )

• ( -2 , -9 )

• ( 9 , -2 )

• ( -9 , 2 )

Triangle ABC is dilated by a scale factor of 4.

What will be the length of B'C'

• 8

• 12

• 4

• 2

If a point is dilated by a scale factor of 5 and the resulting point is (35,20) what was the original point?

• ( 30 , 15 )

• ( 40 , 25 )

• ( 175 , 100 )

• ( 7 , 4 )

• ( 18 , 27 )

• ( 8 , 12 )

• ( 12.66 , 18.66 )

• ( 22 , 34 )

Dilate (5,9) by a scale factor of 3
