100
The coefficient of x for linear equations in slope-intercept form
What is the slope?
100
The values of x where |x| = 4/3
What is -4/3 and 4/3?
(negative four thirds and positive four thirds)
200
The troughs and peaks, the high-points and low-points, the change from positive slope to negative slope or vice versa
What are relative extrema?
200
The input or numbers we are allowed to put INTO a function
What is the domain?
200
The domain and range for all LINEar functions in interval notation
What is (-∞ ,∞ ) ?
(negative infinity to positive infinity)?
200
The b-term for equations in slope-intercept form
What is the y-intercept?
200

300
The origin
What is the location of both the x and y intercepts?

300
The values of x that would make this equation true:
|x-3|=7
What is -4 and 10?
(x equals ten and x equals negative four)
