Finding Slope From Two Points

Front

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

Back

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

Front

Find the slope of the line that passes through: (5, -10) and (5, -4)

Back

Front

What does it mean if the slope of a line is 0?

Back

The line is horizontal.

Front

What does it mean if the slope of a line is undefined?

Back

The line is vertical.

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

The line rises from left to right.

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

The line falls from left to right.
