Initial Practice: Matching a Graph of a
Straight Line with its Equation

Consider the graph at the right containing three lines. Which of the following equations matches the lines A, B, and C.

  1. y = 4 + (1/3) x
  2. y = 6
  3. y = -1/3 + 4 x
  4. y = x + 6
  5. y = 4 - (1/3) x
  6. y = (3/2)x + 2
