A) Translation left and up B) Reflection over the x-axis C) Dilation with a scale factor of 2 D) Rotation 90 degrees clockwise
- 2. I preserve orientation. My pre-image and image will be similar. I can be represented by (nx, ny), where "n" is any number greater than one. What am I?
A) Dilation, reduction B) Reflection over the y-axis C) Rotation clockwise 180 degrees D) Dilation, enlargement
- 3. I will not change the size of a figure. I will not change the way a shape is facing. I can be represented by (x - n, y). What am I?
A) Translation down B) Translation right C) Translation left D) Translation up
- 4. I will not change the size of a figure. I will change the orientation of a figure. I can be represented by (- x, - y). What am I?
A) Reflections over the x-axis B) Rotation 90 degrees clockwise C) Rotation 180 degrees D) Reflection over the y-axis
- 5. The table shows the coordinates of a figure that has been transformed. Which is the correct description of the transformation?
A) Reflection over the x-axis B) Translation 4 units left, two units down C) Translation 10 units left and 4 units down D) Rotation 180 degrees clockwise
- 6. Find the rate of change and the y-intercept for the table shown.
A) m = 3; b = - 8 B) m = 8; b = -3 C) m = -3; b = 8 D) m = - 8; b = 3
- 7. A cooler contains 3.5 gallons of water and is filling up at a rate of 0.1 gallons per second. A second cooler contains 7 gallons of water and is draining at a rate of 0.25 gallons per second. Write and solve an equation to determine the number of seconds, x, it would take for each cooler to contain the same amount of water.
A) 3.5x + 0.1 = 7x - 0.25; x = 0.1 B) 3.5 + 0.1x = 7 + 0.25x; x = - 23.3 C) 3.5 + 0.1x = 7 - 0.25x; x = 10 D) 3.5 - 0.1x = 7 + 0.25x; x = - 10
