Find slope

Front

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

Back

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

Front

Front

Find the slope of the points (-2,3) and (4,-5).

Back

-4/3

Front

What does it mean if the slope is undefined?

Back

The slope is undefined when the line is vertical, meaning the x-coordinates are the same.

Front

Find the slope of the points (-4,5) and (-4,2).

Back

undefined

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

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

Back

A positive slope indicates that 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

A negative slope indicates that the line falls from left to right.
