Front

What does the term 'x-intercept' refer to?

Back

The point where the line crosses the x-axis.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.
