For the following straight line equation, state what is the rate of change?
For the following straight line equation, state what is the rate of change?
To solve this problem, we need to determine the rate of change of the linear equation given by:
The standard form for a linear equation is:
where represents the slope of the line. The slope indicates the rate of change of the function, which describes how much the value of changes for a unit change in .
In the equation , the slope is . This means that for every unit increase in , the value of decreases by 4. Thus, the rate of change for this equation is .
Therefore, the rate of change is .
