Reflection
What are the coordinates after a reflection across the x-axis from (1,1)
(1,-1)
Which transformation do we flip the image?
reflection
What is a translation ?
the sliding of a point on a coordinate plane
What is a dilation?
A dilation is the growing or shrinking of a shape
Solve for x:
2x - 4 = 12
x = 8
Which transformation do we slide the image?
translation
What is the rule of translation going from (1,1) to (2,2)
(x+1,y+1)
What is the thing used to determine the size of the image?
A scale factor
Jayden went to McDonalds and bought a 10 piece nugget combo that cost him $8.50. If the sales tax is 5%, what will be the final cost?
$8.93
What is the final coordinates after (-2,-4) is reflected over the y-axis?
(2,-4)
Which transformation do we change the size of the image?
dilation
Is the rule for a translation always the same?
If i used a scale factor of 2 how much bigger would the shape get?
Double the size
Simplify the expression:
14z + 5 - 2z + 3z - 12
15z - 7
What is the rule for a reflection for (x,y) across the y-axis?
(-x,y)
What are the new coordinates of point (2,-3) after a reflection over the y-axis and a translation of (x+1,y+2)?
(-1,-1)
Starting at the origin if translate x+5 and y+12, what are your new coordinates?
(5,12)
If i used a scale factor of 1, would the shape get bigger or smaller?
It would stay the same size
There are 2 green marbles, 5 blue marbles, and 3 red marbles in a bag. What is the probability that Kira will draw a green marble from the bag? Write your answer as a percent.
20% (2/10)
If (x,-y) is reflected across the x-axis what is the ending coordinate?
(x,y)
Triangle ABC with point (1,2), (1,5), (4,2). Which quadrant will Triangle ABC be in after it is translated 6 units left and 1 unit up?
Quadrant II
Starting at the origin what is (x-9,y-3)
(-9,-3)
If the scale factor going from the pre-image to the image is 5, then what is the scale factor going from the image to the pre-image?
1/5
