Solution Steps

Step 1: Identify the direction of the line

Examine the graph of the line to determine if it is rising, falling, horizontal, or vertical.

Step 2: Determine the slope based on the direction
  • If the line is rising from left to right, the slope is positive.
  • If the line is falling from left to right, the slope is negative.
  • If the line is horizontal, the slope is zero.
  • If the line is vertical, the slope is undefined.
Step 3: Classify the slope

Based on the direction identified in Step 1, classify the slope as positive, negative, zero, or undefined.

Final Answer

The slopes are classified as follows:

  • Line 1: Positive
  • Line 2: Negative
  • Line 3: Zero
  • Line 4: Undefined
