x and y intercepts

Front

What is the definition of the x-intercept?

Back

The x-intercept is the point where a graph crosses the x-axis, meaning the value of y is zero.

Front

What is the definition of the y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis, meaning the value of x is zero.

Front

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

Back

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

Front

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

Back

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

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.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x; it indicates how steep the line is.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the significance of the point (0, b) in a linear equation?

Back

The point (0, b) represents the y-intercept of the line.

Front

What is the significance of the point (a, 0) in a linear equation?

Back

The point (a, 0) represents the x-intercept of the line.

Front

If a line has a slope of 0, what can be said about the line?

Back

A line with a slope of 0 is horizontal and does not rise or fall.
