Identifying the y-intercept from a graph

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis on a graph. It represents the value of y when x is 0.

Front

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

Back

To find the y-intercept, look for the point where the line intersects the y-axis. The y-coordinate of this point is the y-intercept.

Front

If a line crosses the y-axis at (0, 100), what is the y-intercept?

Back

The y-intercept is 100.

Front

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

Back

The y-intercept is 0.

Front

What does a negative y-intercept indicate?

Back

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

Front

If a line crosses the y-axis at (0, -4), what is the y-intercept?

Back

The y-intercept is -4.

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 0 in a linear equation.

Front

How can you determine the y-intercept from the equation of a line in slope-intercept form (y = mx + b)?

Back

In the equation y = mx + b, 'b' represents the y-intercept.

What is the y-intercept of the line represented by the equation y = 2x + 6?

Back

The y-intercept is 6.

Front

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

Back

The y-intercept is 2.
