1
Warm-up Is the following set of ordered pairs a function? Explain why or why not. {(-1, -2), (0, 2), ( 1, 4), (3, 8)} Make a table, or T-chart, using the following domain values for the given function. Domain values: {-2, -1, 0, 1, 2} y= -3x + 9 Is the function in #2 linear? Explain.

2
**Are arithmetic sequences also linear functions?**

Can we take a sequence and write it as a set of ordered pairs? The term position is my x-value and the value of the term at that position is my y-value. So lets look at the following sequence: 3, 7, 11, 15, … We can write this sequence as a set of ordered pairs to determine if it can be a function. {(1, 3), (2, 7), (3, 11), (4, 15), …}

3
**Are arithmetic sequences also linear functions?**

Is this set of ordered pairs a function? Why or why not? {(1, 3), (2, 7), (3, 11), (4, 15)} Can we figure out the function for these ordered pairs? Let’s graph this function on a coordinate plane to see if it’s linear.

4
**Are arithmetic sequences also linear functions?**

Graph the ordered pairs and overlay with a line. {(1, 3), (2, 7), (3, 11), (4, 15)}
