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

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, y).

Front

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

Back

Look for the point where the line intersects the y-axis.

Front

What does the coordinate (0, 2) represent?

Back

It represents a y-intercept of 2, meaning the line crosses the y-axis at 2.

Front

If a line has a y-intercept of (0, -1), what does this mean?

Back

The line crosses the y-axis at -1.

Front

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

Back

The y-intercept is 3, represented as (0, 3).

Front

What is the y-intercept of the line represented by the equation y = -4x + 1?

Back

The y-intercept is 1, represented as (0, 1).

Front

If a line does not cross the y-axis, what can be said about its y-intercept?

Back

The y-intercept is undefined.

Front

What is the y-intercept of the line graphed below? (Assume it crosses at 4)

Back

The y-intercept is 4, represented as (0, 4).

Front

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

Back

Look for the value of y when x = 0.

Front

What is the y-intercept of the line represented by the equation y = -2x - 5?

Back

The y-intercept is -5, represented as (0, -5).
