1. Identify Linear Relationships

2. Linear Relationship – a relationship between two quantities that have a constant rate of change. when graphed it forms a straight line In a table – the value of x changes at a constant rate – the value of y changes at a constant rate

3. Determine if each table has a linear relationship EX1) XY -33 015 327 639 3 3 3 12 Rate of change is y/x 12/3= 4 EX2) XY -1413 -717 021 724 7 7 7 4 4 3 Yes Linear No not Linear

4. Graph the relationship to determine if there is a linear relationship. EX3) s A square has a side length of s. Graph the relationship of the perimeter and area to its side to determine if the relationships are linear. Side (s) Perimeter Area 3214 128416 941

5. Side (s)1234 Perimeter481216 Area14916 Perimeter is linear to side Area is not linear to side Side 1234 perimeterperimeter 4 8 12 16 areaarea
