Question

(06.02 LC) Line AB contains points A (1, 2) and B (−2, 6). The slope of line AB is (4 points) zero undefined positive negative

Answer 1

Points which lie on line AB are A(1,2) and B (-2,6).

Slope of line joining two points $(x_{1},y_{1})$ and  $(x_{2},y_{2})$ is = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

So, Slope of line joining AB = $\frac{6-2}{-2-1}=\frac{-4}{3}$

So, Slope of line AB is negative rational number.

Option (D) Negative ,is true option regarding slope of line AB.

Answer 2

Answer:

The slope is -4/3.

D. negative

Step-by-step explanation:

Slope formula:

$\displaystyle\frac{y_2-y_1}{x_2-x_1}$

$\displaystyle \frac{6-2}{(-2)-1}=\frac{4}{-3}=-\frac{4}{3}$

$\Large\textnormal{The slope is -4/3.}$
