Step-by-Step Solution

To determine the rate of change of the function given by the equation y=2x+1 y = -2x + 1 , we will follow these steps:

  • Step 1: Recognize that the equation is written in slope-intercept form, y=mx+b y = mx + b , where m m is the slope, or rate of change.
  • Step 2: Identify the coefficient of x x in the given equation. Here, the equation y=2x+1 y = -2x + 1 reveals that the coefficient of x x is 2-2.

This coefficient 2-2 directly represents the slope m m of the function.

Therefore, the rate of change of the function is m=2 m = -2 .

Answer

m=2 m=-2
