How do you locate rate of change on a graph?
Find the slope of the tangent to the graph at the point of interest.
If Jenny's car uses less gas per mile driven than Sandra's truck how does the graph representing the rate of change of Sandra's truck compare to the graph representing the rate of change of Jenny's ca?
The answer depends on the rate of change of WHAT? The rate of change of the gas used? the rate of change of the gas left, the rate of change of the range that the vehicle will go? The question is too vague.
How do you determine if a rate of change is constant?
You can determine if a rate of change is constant, by taking the instantaneous rate of change at multiple points - if they are all equal to each other, it can be assumed that the rate of change is constant. Alternatively, you can differentiate the function (if there is an associated function) - if this comes to a constant i.e. a number, then the rate of change is constant.
Why can slope be referred to as rate of change?
Slope can be referred to by rate of change because it is the rate that x changes compared to y on a graph.
What is constant rate of change?
When something has a constant rate of change it means that it has a linear graph. The function can be written in the slope intercept form of y = mx + b.
