Find the Rate of Change: Analyzing y=-3/8-4x Linear Equation

To determine the rate of change for the given line equation, we recognize that the equation $y = -\frac{3}{8} - 4x$ is in the slope-intercept form $y = mx + b$, where $m$ is the slope and represents the rate of change.

In the equation provided, the term $-4x$ indicates that the slope or rate of change is $m = -4$.

Thus, the rate of change of the given straight line is $-4$.

Comparing this to the provided choices, the correct answer is:

• Choice id "2": $-4$

Therefore, the rate of change for the linear equation is $-4$.
