Chapter 4: Q. 285 (page 496)

What does the sign of the slope tell you about a line?

Short Answer

Expert verified
  • For positive slope, as we go from left to right, the rise increases.
  • For negative slope, as we go from left to right, the rise decreases.

Step by step solution

01

Step 1. Given Information

It is known that the slope is the ratio of the rise to the run.

02

Step 2. Classify according to the sign of the slope

  • If the slope is positive, it implies that the rise is positive for positive run.
  • So, as we go from left to right, the rise increases.
  • If the slope is negative, it implies that the rise is negative for positive run.
  • So, as we go from left to right, the rise decreases.
