# Line AB contains points A (1, 2) and B (-2, 6). The slope of line AB is___.

Zero, Undefined, Positive, Negative

**Solution:**

From the question, it is given that, line AB contains points A (1, 2) and B (-2, 6)

The slope when the two points are given is calculated as:

m = Rise / Run

= Change in y coordinates/ change in x coordinates

= (y_{2} - y_{1})/ ( x_{2} - x_{1})

Substituting the values, we get

= (6 - 2)/(-2 - 1)

= -4/3

= negative

Therefore, the slope of line AB is negative.

## Line AB contains points A (1, 2) and B (-2, 6). The slope of line AB is___.

**Summary:**

If line AB contains points A (1, 2) and B (-2, 6) then the slope of line AB is negative.
