Finding Intercepts

Front

What is a y-intercept?

Back

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

Front

What is an x-intercept?

Back

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

Front

How do you find the y-intercept from a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

How do you find the x-intercept from a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

What does the ordered pair (0, 4) represent on a graph?

Back

The ordered pair (0, 4) represents a y-intercept at the point where the line crosses the y-axis at y = 4.

Front

What does the ordered pair (9, 0) represent on a graph?

Back

The ordered pair (9, 0) represents an x-intercept at the point where the line crosses the x-axis at x = 9.

Front

If a line has a y-intercept of (0, -6), what does this indicate?

Back

This indicates that the line crosses the y-axis at the point (0, -6).

Front

What is the significance of intercepts in graphing linear equations?

Back

Intercepts help to determine the position of the line on the graph and are essential for sketching the graph accurately.

Front

Can a line have both x-intercept and y-intercept?

Back

Yes, a line can have both an x-intercept and a y-intercept unless it is vertical or horizontal.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C, where A, B, and C are constants.
