Front

Two lines that are perpendicular have slopes that are...

Back

opposite reciprocals.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

If a line has a slope of 0, what does this indicate about the line?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does this indicate about the line?

Back

The line is vertical.

Front

What is the relationship between the slopes of two parallel lines?

Back

The slopes of parallel lines are equal.
