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. It is represented as (0, y).

Front

How do 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. The x-coordinate at this point is always 0.

Front

What does the coordinate (0, 3) represent?

Back

The coordinate (0, 3) represents a point on the graph where the y-intercept is 3.

Front

If a line has a y-intercept of -2, what is the coordinate?

Back

The coordinate for a y-intercept of -2 is (0, -2).

Front

What is the y-intercept of the line represented by the equation y = 2x + 3?

Back

The y-intercept is 3, which is the value of y when x = 0.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept indicates the starting value of y when x is zero, providing insight into the behavior of the line.

Front

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

Back

Look for the row where x = 0; the corresponding y value is the y-intercept.

Front

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

Back

The y-intercept is 4, which is the value of y when x = 0.

Front

If a graph shows a line that crosses the y-axis at (0, -1), what is the y-intercept?

Back

The y-intercept is -1.

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.
