Front

What is the slope of the equation y = -3x + 4?

Back

-3

Front

How is slope calculated?

Back

Slope is found by counting Rise over Run.

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the change in y over the change in x.

Front

If a line has a slope of 0, what does that indicate?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate?

Back

The line is vertical.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the 'm' represent in the slope-intercept form?

Back

The slope of the line.
