How can you tell if a graph is proportional?
IT TOUCHES THE ORIGIN!!
100
What does the letters "m" and "b" mean in y=mx+b?
m= SLOPE
b= Y-INTERCEPT
100
Is the following represent a proportional or non-proportional function? EXPLAIN
y=-2x
What is Proportional?
*because it only has the SLOPE and no y-intercept*
y-intercept = 0 here
100
D
Because each x-value only has one y-value (or one line).

Is the following proportional or non-proportional?
proportional

How can you tell if a table is non-proportional?
The "b" does NOT equal 0.
200
Is the following represent a proportional or non-proportional function? EXPLAIN
y=-3x+1/2
What is non-proportional?
There is a y-intercept of 1/2
b= 1/2

1. Which representation of a transformation on a coordinate grid does not preserve congruence?
A. (x,y) → (x+4, y-3)
B. (x,y) → (-y,x)
C. (x,y) → (-x,y)
D. (x,y) → (2x, 2y)
D -- bc its being MULTIPLIED = DILATION
congruence -- stays the same shape and SIZE

What is the coordinate for the origin?
(0,0)
300
Is the following proportional or non-proportional?
EXPLAIN
Proportional, because the y-intercept is 0
b=0
300
what makes an equation PROPORTIONAL?
When it only includes the slope, or 'a' or 'm' -- there is no y-intercept or 'b'.
y=ax
300
A - the only one to pass the vertical line test

How can you tell if a graph is proportional??
AFTER PUTTING THE NUMBERS IN THE CALCULATOR:
the y-intercept is 0
OR
b=0

Does the following situation describe a proportional or non-proportional relationship?
The total surface area of a cylinder with a radius of 1 unit and height of x units can be represented by
y= 2πx + 2π.
400
what is the slope and y-intercept?
y=12-5x
m=-5
b=12

How can you tell if a graph is non-proportional?
it does NOT touch the origin
500

EXPLAIN
Non-proportional because the y-intercept is -5
b= -5
