And you see very clearly that the slope here, the rate of change of y with respect to x is negative 4. Use the slope-intercept form to find the slope and y-intercept. We have y=5x-x^2. The rate of change is the rate at which y-values are changing with respect to the change in x-values. What is the rate of change of its y-coordinate when x=2? The shortened version of it is the derivative of a function - how fast the function is changing. To find instantaneous rate of change, we simply take the derivative of our function, evaluate it at the point in question, and boom, we're done. The slope is equal to 100. Example 2: Rate of Change (remember y = mx + b? However, if one wishes to find the average rate of change over an interval, one must find the slope of the secant line, which connects the endpoints of the interval.
