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).
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.
Find the derivative
Find the slope of the tangent to the graph at the point of interest.
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 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.
To determine the rate constant from a graph, you can use the slope of the line in a first-order reaction plot. The rate constant is equal to the negative slope of the line, which can be calculated by dividing the change in concentration by the change in time.
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.
To find the unit rate or constant of proportionality from a graph, identify two points on the line that represents the proportional relationship. Calculate the change in the y-values (output) and the change in the x-values (input) between these two points. The constant of proportionality is then found by dividing the change in y by the change in x, resulting in the slope of the line. This slope indicates the unit rate of the relationship.
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.
To find the constant rate of change is by taking the final minus initial over the initial.
Find the derivative
Find the slope of the tangent to the graph at the point of interest.
To find the rate of change on a graph, you can identify two points on the curve and calculate the difference in the y-values (vertical change) divided by the difference in the x-values (horizontal change) between those points. This is often referred to as the slope of the line connecting the two points. For linear graphs, this slope remains constant, while for nonlinear graphs, the rate of change can vary at different intervals. You can also use calculus to find the instantaneous rate of change by determining the derivative of the function at a specific point.
Differentiate the graph with respect to time.
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.
You find the average rate of change of the function. That gives you the derivative on different points of the graph.
