Chapter 1: Q. 143 (page 44)

A student is asked to find the slope of the line joining (-3, 2) and (1, -4). He states that the slope is $\frac{3}{2}$ . Is he correct? If not, what went wrong?

Short Answer

Expert verified

No. he is incorrect the slope of the line is $- \frac{3}{2}$

Step by step solution

Given information

The given points are $A (- 3, 2), B (1, - 4)$

Find the slope

We get,

$S l o p e = \frac{- 4 - 2}{1 - (- 3)} S l o p e = \frac{- 6}{4} S l o p e = - \frac{3}{2}$

Conclusion

No he is not correct. he did not consider the negative sign occured during the calculation. The slope of the line passing through the given point is $- \frac{3}{2}$ .
