LINEAR RATE OF CHANGE- Day 4 EOC Test Strategy LINEAR RATE OF CHANGE- Day 4

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.

TEST STRATEGY- Mark the Question. Sometimes the question will state ONLY two points to look at instead of the whole table. So –MARK just those two points on THE TABLE & the Rate of Change.

EXAMPLE #4.1 The table below shows the number of seconds that Kailey held a plank for a training period. What is the average rate of change in the number of seconds Kailey held a plank from day 2 to day 5? Day Time (seconds) 1 80 2 75 3 90 4 110 5 105

You Try: (wkst #4) *Mark the text to indicate how you know this is a linear rate of change problem. *Mark the question & the corresponding values on the table. *Find the rate of change. *Spoiler Alert: #5 is slightly different!
