(6,-5)
What is a function?
When the x values doesn't repeat it's a function.

DoubleOGlizzy had a small switch and he wanted dilate his switch to make it bigger. What type of dilation would he need to make his switch bigger and what's the rules when shapes get bigger?
Enlargement= greater then 1 or a IPF

$1830
If a shape gets bigger what could be the rule ? And why are the others wrong?
A.(.2x,.2y)
B. (5y,5x)
C.(7/3x,7/3y)
D.(x+12,y+12)
C
A=less then 1
B= the y and x are flipped
D=translation
What transformations preserves congruence?
Rotation, Reflection, Translations
What's Mr.Thomas Birthday?
Jan. 25
If the slope is negative does that mean the y-intercept is negative? Explain?
No. The slope is the rate of change and has nothing to do with the y-intercept.
How do we know the slope and y-intercept of a word problem?
The slope is found by locating key words such as (each, every, or per) and the y-intercept is the number that's either the starting point or the number that will not change.
What is A dilation? Tell me everything you know?
Dilation makes a shape bigger or smaller.
Dilation=Multiplication
Reduction is when the shape gets smaller because the scale factor is less than 1 or a regular fraction.
Enlargement is when the shape gets bigger and the scale factor is greater than 1 or a IPF.
