slope and y-intercept

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm' in the equation of a line (y = mx + b). It is calculated as the change in y divided by the change in x (rise/run).

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis. It is represented as 'b' in the equation of a line (y = mx + b) and can be found by setting x to 0.

Front

Identify the slope in the equation y = 4x - 2.

Back

The slope is 4.

Front

Identify the y-intercept in the equation y = -3x + 7.

Back

The y-intercept is 7.

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

The slope is 2.

Front

Determine the slope and y-intercept from the equation y = 1/2x + 4.

Back

Slope: 1/2, y-intercept: (0, 4).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

Identify the slope in the equation y = -5x + 1.

Back

The slope is -5.

Front

Identify the y-intercept in the equation y = 2/3x - 4.

Back

The y-intercept is -4.
