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

How do you identify the y-intercept from a graph?

Back

Look for the point where the line intersects the y-axis; this point will have an x-coordinate of 0.

Front

What does the coordinate (0, y) represent?

Back

It represents a point on the y-axis, where 'y' is the value of the y-intercept.

Front

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

Back

The y-intercept is 3.

Front

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

Back

The y-intercept is 4.

Front

If a graph shows a y-intercept at (0, -2), what does this indicate?

Back

It indicates that the line crosses the y-axis at -2.

Front

What is the y-intercept of the line graphed below? (0, 1), (0, -2), (0, 0), (0, 3)

Back

The y-intercept is (0, 1).

Front

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

Back

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

Front

What is the y-intercept of the line represented by the equation y = -x + 1?

Back

The y-intercept is 1.
