Slope and Intercepts of Lines

Front

What is the x-intercept of a line?

Back

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

Front

What is the y-intercept of a line?

Back

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

Front

In the equation y = mx + b, what does 'm' represent?

Back

The slope of the line.

Front

In the equation y = mx + b, what does 'b' represent?

Back

The y-intercept of the line.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you write the equation of a line in slope-intercept form?

Back

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

Front

What is the slope of the line represented by the equation y = -2x + 2?

Back

The slope is -2.

Front

What is the x-intercept of the line represented by the equation y = 3x + 6?

Back

The x-intercept is (-2, 0).
