Math Problem Statement
What is the y-intercept
Solution
The y-intercept is the point where a graph intersects the y-axis. In other words, it is the value of when in a given equation. For a linear equation in slope-intercept form, , the y-intercept is the constant .
For example:
- In the equation , the y-intercept is 3, meaning the graph crosses the y-axis at .
