Slope and Y-intercept

Front

What is the slope of a line?

Back

The slope of a line is a number that describes how steep the line is. It is calculated as the rise (change in y) over the run (change in x).

Front

What does the letter 'm' represent in the equation y = mx + b?

Back

The letter 'm' represents the slope of the line.

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 (0, b) in the equation y = mx + b.

Front

How do you find the slope between two points?

Back

To find the slope between two points (x1, y1) and (x2, y2), use the formula: slope = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of the line y = 2x + 3?

Back

The y-intercept is (0, 3).

Front

If a line has a slope of -2, what does that mean?

Back

A slope of -2 means that for every 1 unit you move to the right, the line goes down 2 units.

Front

What is the slope of the line y = -4x + 10?

Back

The slope is -4.

Front

What is the y-intercept of the line 3x + y = 12?

Back

The y-intercept is 12.

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.
