10/27 Identify Y-intercept from a graph and tables

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph.

Front

What are the coordinates of the y-intercept?

Back

The coordinates of the y-intercept are always in the form (0, y), where y is the value at which the line crosses the y-axis.

Front

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

Back

To find the y-intercept from a graph, look for the point where the line intersects the y-axis.

Front

How can you find the y-intercept from a table of values?

Back

In a table of values, the y-intercept is the value of y when x is 0.

Front

If a line crosses the y-axis at (0, 3), what is the y-intercept?

Back

The y-intercept is 3.

Front

If a line crosses the y-axis at (0, -2), what is the y-intercept?

Back

The y-intercept is -2.

Front

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

Back

A positive y-intercept indicates that the line starts above the origin on the y-axis.

Front

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

Back

A negative y-intercept indicates that the line starts below the origin on the y-axis.

Front

What is the y-intercept of the line represented by the equation y = 2x + 4?

Back

The y-intercept is 4.

Front

What is the y-intercept of the line represented by the equation y = -3x - 5?

Back

The y-intercept is -5.
