Y Intercept

Front

What is the y-intercept?

Back

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

Front

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

Back

The y-intercept can be found by identifying the value of y when x is 0.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.

Front

What does a slope of zero mean?

Back

A slope of zero means that the line is horizontal and there is no change in y as x changes.

Front

What does an undefined slope mean?

Back

An undefined slope occurs in a vertical line where x does not change, resulting in a division by zero.

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

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

Back

The y-intercept can be found by locating the point where the line intersects the y-axis.

Front

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

Back

The y-intercept is 1, which is the value of y when x = 0.

Front

If a line has a y-intercept of (0, -2), what does this mean?

Back

It means that the line crosses the y-axis at the point (0, -2).
