Front

What is a horizontal line's equation?

Back

y = k, where k is a constant.

Front

What is a vertical line's equation?

Back

x = k, where k is a constant.

Front

How do you create a table of values for a linear equation?

Back

Choose several x-values, substitute them into the equation to find corresponding y-values, and list the pairs.

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the significance of the x-intercept in a graph?

Back

The x-intercept is the point where the line crosses the x-axis.

Front

How can you determine if a line is horizontal or vertical from its equation?

Back

If the equation is of the form y = k, it is horizontal; if it is of the form x = k, it is vertical.

Front

What is the general form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.
