Is the function y = 3x + 4 linear or nonlinear?
Linear
200
What is the slope and y-intercept of the line
y = 3x + 2
slope = 3 y-intercept = 2

Describe Mr. Slope Guy's nose and what it stands for.
A vertical line with a U shape underneath it. This means that the vertical line's slope is undefined.

True or False.
Linear equations are always straight lines.
TRUE

How can you identify linear vs. nonlinear in an Equation?
It must be in the form of y=mx+b to be counted as linear.
Nonlinear has exponents, square roots, random stuff that isn't normal.
300
What is the slope and y-intercept of the line:
y=-1/4x - 6
Slope = -1/4 y-intercept = -6

What is at the end of Mr. Slope Guy's mouth? And what does it stand for?
Zeros- or circles- but it means that a horizontal line has a zero slope.

How do we find slope on a graph?
Rise over Run

Is the function y = sqrt( 3x) +4 linear or nonlinear?
Nonlinear. Remember, it has to be in y=mx +b, where m is multiplied by x. In this equation, x is being square-rooted.

What is the slope and y-intercept of the following equation: y=-x + 3
Slope = -1 y-intercept = 3

Describe Mr. Slope Guy's eyes & eyebrows.
Left side - positive sign with his eyebrow angled up (from left to right) and the right side is a negative sign with the eyebrow going down (L to R).

Random reward-- pick 1 person in the room (can't be yourself).
If you picked someone in your group- then you each get candy. (and no points rewarded)
If you picked someone else- they get candy and your group gets 500 points!
