X and Y intercepts

Front

What is the x-intercept of a graph?

Back

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

Front

What is the y-intercept of a graph?

Back

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

Front

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

Back

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

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 does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x, indicating the steepness and direction of the line.

Front

If a line has a positive slope, what does that indicate about the x and y values?

Back

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

Front

If a line has a negative slope, what does that indicate about the x and y values?

Back

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

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.
