Represent a Linear Relationship
A linear pattern changes by a constant amount and appears as a straight line when its ordered pairs are graphed.
The big idea
A linear rule combines rate and starting value
The rule y = 4x + 3 has a constant rate of 4 and an initial value of 3. Each increase of 1 in x adds 4 to y.
Work it through
Use y = 4x + 3 when x = 6
- 1. Replace x with 6: y = 4(6) + 3.
- 2. Multiply: y = 24 + 3.
- 3. Add: y = 27.
- 4. Plot (6, 27) and verify it follows the table's constant change.
