LINEAR RATE OF CHANGE- Day 2

2. TEST STRATEGIES FOR LINEAR RATE OF CHANGE
1). Recognize key terms & formats for linear rate of change.
2). Identify whether a problem will use linear rate of change.
3). Read the table to find the linear rate of change.
4). Read the table to find the linear rate of change w/out incremental change in x.
5). Read the table to find the linear rate of change between specified pts.
6). Interpret rate of change in context
7). Extend table to find equation
8). Use calculator to find equation.
9). Interpret the constant & coefficient.
10). Finding specific range value for a given domain value.
11). If no table is given, create one.
12). Relate recursive to tables & explicit form.
13). Reverse from explicit to recursive form.

3. Review: KEY words for LINEAR RATE of CHANGE
EACH EVERY
RATE PER
There are others that are not as common: monthly, weekly, daily, a, average…

4. Review KEY features for LINEAR RATE of CHANGE
*Look for equation or functions in slope-intercept form:
y =mx + b OR f(x) = mx + b
*If you see a table & there are
no other hints – check the rate
of change in y column. x
f(x) -1 6 1 4 3 2
