Performing transformations

Suppose a constellation of stars is plotted on a coordinate plane. The coordinates of one star are (–2, 1). The star is translated up 5 units. What are its new coordinates?

• (-2, 6)

• (-7, 1)

• (3, 1)

• (-2, -4)

Which graph shows a translation?

• 
• 
• 
• 

Describe the transformation:

(x, y) -> (x, y-2)

• Translation 2 units to the left

• Translation 2 units up

• Translation 2 units to the right

• Translation 2 units down

Which of the following shows a translation?

• 
• 
• 
• 

Describe the transformation shown

• Reflection across the x axis.

• Translation down 6 and left 1

• Dilation by a factor of 2/3

• Rotation of 180^o

translation

• (x, y) --> (-y, x)

• (x, y) --> (-x, -y)

• (x, y) --> (y, -x)

• (x, y) --> (x +r/-l, y +u/- d)

• (x, y) --> (cx, cy)

What is the vertical shift of this equation?
f(x) = -(x + 3)² - 5

• left 5
• right 5
• up 5
• down 5

A figure in Quadrant II was transformed, and

the image is in Quadrant III. Which could not

have been the transformation?

• A rotation 90° clockwise

• A reflection over the x-axis

• A translation down

• A rotation 270° clockwise

Where would point J' be if you translated point J 5 units to the left and 2 units up?

• (5, 3)
• (3, -5)
• (-5, 3)
• (-3, 5)
