Y Intercept

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 find the y-intercept from a graph?

Back

Look for the point where the line intersects the y-axis. The coordinates will be in the form (0, y).

Front

What does the point (0, 1) represent on a graph?

Back

It represents the y-intercept, meaning the line crosses the y-axis at y = 1.

Front

What does the point (0, 3) indicate on a graph?

Back

It indicates that the y-intercept is at y = 3, where the line crosses the y-axis.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run.

Front

What does an undefined slope mean?

Back

An undefined slope occurs when a line is vertical, meaning it does not have a defined rise over run.

Front

What does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line, meaning there is no rise as you move along the line.

Front

If a line has a positive slope, what does that mean?

Back

A positive slope means that as you move from left to right, the line rises.

Front

If a line has a negative slope, what does that mean?

Back

A negative slope means that as you move from left to right, the line falls.

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 in a linear equation.
