What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, b) where b is the value of y when x = 0.

Front

What is the formula for finding the slope of the line containing (x1, y1) and (x2, y2)?

Back

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

What is the equation used to solve for 'x' in the context of the Pythagorean theorem?

Back

Front

What is the x-intercept of the equation 3x + 8y = 24?

Back

The x-intercept is (8, 0).

Front

Define slope in the context of a linear graph.

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

What does the point (0, b) represent in a linear equation?

Back

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

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the direction and rate of change of the line; a positive slope means the line rises, while a negative slope means it falls.

Front

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

Back

A horizontal line has a slope of 0, while a vertical line has an undefined slope.
