You measure the change in the vertical direction (rise) per unit change in the horizontal direction (run).
The rate of change is constant between A and B if AB is a straight line.
Take any two points, A = (xa, ya) and B = (xb, yb)
then the average rate of change, between A and B = (yb- ya)/(xb- xa).

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.
How do you find rate of change if change is not constant?
Find the derivative
How do you locate rate of change on a graph?
Find the slope of the tangent to the graph at the point of interest.
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.
The rate of change of any nonlinear function is constant?
No. Only a linear function has a constant rate of change.No. Only a linear function has a constant rate of change.No. Only a linear function has a constant rate of change.No. Only a linear function has a constant rate of change.
How do you tell whether a graph shows a constant or variable rate of change?
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
How do you know if a function has a constant or variable rate of change?
If the graph is a non-vertical straight line, then the rate of change is constant. If the line is curved, then the rate of change (slope) varies.
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.
How to find the constant rate of change?
To find the constant rate of change is by taking the final minus initial over the initial.
How do you find rate of change if change is not constant?
Find the derivative
How do you locate rate of change on a graph?
Find the slope of the tangent to the graph at the point of interest.
What would the graph look like on a position verse time plot with constant acceleration?
If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.
How do you find the rate of change from graphs?
Differentiate the graph with respect to time.
How does the graph of an exponential function differ from the graph of a linear function and how is the rate of change different?
The graph of a linear function is a line with a constant slope. The graph of an exponential function is a curve with a non-constant slope. The slope of a given curve at a specified point is the derivative evaluated at that point.
How do you graph trigonometric functions?
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
