Transformations
What are the 3 main types of transformations we have learned?
Translations, Rotations, Reflections
Name the property that we have talked about in class. When we multiply a number outside of the parentheses to the terms inside the parentheses.
Distributive Property
What can I do to emphasize important information in the scenario?
Underline or highlight
What does x = x tell me?
Infinitely Many Solutions
What is GLO #1?
Self-Directed Learner
Match the meaning with the word.
1) Rotate 1) Flip
2) Reflect 2) Slide
3) Translate 3) Spin
Rotate = Spin
Reflect = Flip
Translate = Slide
Apply distributive property to this expression:
5(2x-7)
10x-35
How can I figure out what my variable represents?
Look at what we don't know.
What is the question asking us?
What does x = 7 tell me?
One solution. Only the number 7 makes the equation true.
What is being a self-directed learner? A or B
A) Waiting until someone asks if you need help
B) Going to PAW Time and getting extra help if you need it
B
What does this translation rule mean?
(x, y) -> (x + 2, y - 1)
Right 2 units, Down 1 unit
What is the first step to solving for x in this equation?
2x - 5 = 3
Add 5 to both sides
How can I figure out what my equation is equal to?
Look at what the total is of something.
(Multiple answers are okay)
What does one solution mean?
There is only one value of x that makes the equation true
Give me an example of being a self-directed learner
Multiple answers
Apply this translation rule to the point (0, 5) and (1, -1). What is your new point?
(x, y) -> (x + 2, y - 1)
(2, 4) and (3, -2)
What is the first step to solving for x in this equation?
3(-2x + 10) = -9x - 4
Write an equation to represent this scenario?
Sarah bought a notebook for $3 and some pens that cost $2 each. She spent $15 total. How many pens did she buy?
2x + 3 =15
What does infintely many solutions mean?
There are an endless amount of solutions that make the equation true?
Give me one reason why being a self-directed learner is important?
Multiple answers are okay.
What does the negative sign mean in this rotation rule?
(x, y) -> (-y, x)
The y becomes opposite.
Ex: -5 turns to 5
What is the first step to solving for x in this equation?
-2x + 1 = 3x - 7
Ex) Get your variables/constants on one side
Ex) Add 2x to both sides
Ex) Add 7 to both sides
Write an equation to represent this scenario.
A taxi ride costs $4 plus $0.75 per mile. If the total cost was $13, which equation finds the number of miles?
4 + 0.75x = 13
What does no solution mean?
There is no value of x that makes the equation true
Give me one example of how not being a self-directed learner affects your grade.
Multiple answers okay.
