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. 1. Replace x with 6: y = 4(6) + 3.
  2. 2. Multiply: y = 24 + 3.
  3. 3. Add: y = 27.
  4. 4. Plot (6, 27) and verify it follows the table's constant change.
