Math Problem Statement

Alejandra graphed a linear function. Which ordered pair best represents the location of the y-intercept?

Solution

The problem asks which ordered pair best represents the location of the y-intercept of the given linear function on the graph.

What is a y-intercept?

The y-intercept is the point where the line crosses the y-axis. This means that the x-coordinate will be 0 at this point because the line meets the y-axis when x=0x = 0.

Step-by-step Solution:

  1. Look at the graph: We need to find the point where the line crosses the y-axis.
  2. Identify the point on the y-axis: The line crosses the y-axis at the point where y=2y = 2.
  3. Check the coordinates: The corresponding ordered pair would be (0,2)(0, 2), since the x-coordinate is 0 and the y-coordinate is 2.

Conclusion:

The ordered pair that best represents the location of the y-intercept is (0,2)(0, 2), which corresponds to option B.

Would you like further details on how to identify intercepts or any other part of the solution?

Here are some related questions to further explore:

  1. What is the x-intercept of this linear function?
  2. How can you find the slope of the line from the graph?
  3. Can a line have more than one y-intercept?
  4. How does changing the slope affect the y-intercept of a linear function?
  5. How can you write the equation of the line using the y-intercept and slope?

Tip: For linear equations in the form y=mx+by = mx + b, the value of bb is the y-intercept.
