# How to find the y intercept of a graph

These sites allow users to input a Math problem and receive step-by-step instructions on How to find the y intercept of a graph.

## Meaning, Examples

Find the x and the y intercepts of the graph of function f defined by f (x) = - 3 x + 9 Solution to Example 1 Since a point on the y axis has x coordinate equal to zero, to find the y interecpt, we set x to zero and find the y coordinate which is f (0).
