Front

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

Back

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis.

Front

If a line has a slope of 1/2, what does this mean?

Back

For every 2 units moved horizontally, the line moves up 1 unit.
