What value best represents the y-intercept of the line?
Understand the Problem
The question is asking for the value that represents the y-intercept of the line shown in a graph of a linear function. The y-intercept is the point where the line crosses the y-axis.
Answer
The y-intercept is $-2$.
Answer for screen readers
The y-intercept value is $-2$.
Steps to Solve
- Identify the y-intercept on the graph
Locate the point where the line intersects the y-axis. This is the point where $x = 0$.
- Read the y-coordinate
Once you have located the y-intercept point on the graph, read the corresponding y-coordinate.
- Provide the y-intercept value
The value of the y-coordinate at the identified point represents the y-intercept of the line.
The y-intercept value is $-2$.
More Information
The y-intercept is a key characteristic of a linear function, representing the starting value of the function when $x = 0$. In this case, the line crosses the y-axis at $-2$.
Tips
- Confusing the y-intercept with another point on the line, such as the x-intercept. Make sure to strictly identify the point where the line crosses the y-axis.
