y-intercepts

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It is represented as (0, b), where b is the value of the y-intercept.

How do you find the y-intercept from a linear equation?

Back

To find the y-intercept from a linear equation in the form y = mx + b, identify the value of b, which is the y-intercept.

Front

What does a positive y-intercept indicate about a graph?

Back

A positive y-intercept indicates that the line crosses the y-axis above the origin (0,0).

Front

What does a negative y-intercept indicate about a graph?

Back

A negative y-intercept indicates that the line crosses the y-axis below the origin (0,0).

Front

If a line has a y-intercept of 3, what is the point on the graph?

Back

The point on the graph is (0, 3).

Front

What is the slope of a line with a positive y-intercept?

Back

The slope can be positive, negative, or zero; the y-intercept does not determine the slope.

How can you determine the y-intercept from a graph?

Back

Locate the point where the line intersects the y-axis; this point's y-coordinate is the y-intercept.

If a graph shows a y-intercept of -2, what does this mean?

Back

It means the line crosses the y-axis at the point (0, -2).
