To determine the increase in the y-value for an increase of 1 in the x-value, you typically need a function that relates x and y. This relationship can be expressed in the form of an equation, such as \( y = f(x) \).
The increase in the y-value can be found by calculating the difference in y-values at the two points, \( y = f(x) \) and \( y = f(x+1) \):
\[ \Delta y = f(x+1) - f(x) \]
If you have a specific function, I can help you calculate the change in y when the x-value increases by 1. Please provide the function or more context if you have it!
