Front

Define slope in the context of a graph.

Back

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

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 a negative slope indicate about a line?

Back

A negative slope indicates that the line is decreasing as it moves from left to right.

Front

If the slope of a line is 3/7, what does this mean in terms of rise and run?

Back

For every 7 units run, the line rises 3 units.

Front

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

Back

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