Chapter 3: Q20. (page 179)

Find the slope of the line that passes through each pair of points.
$(- 3, 4), (2, - 6)$

Short Answer

Expert verified

The number $- 2$ represents the required slope.

Step by step solution

Step 1. Determine the formula that can be used.

The slope formula $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ can be used to calculate the required slope.

Step 2. Take the help of the obtained method.

Take the help of formula for slope of a line represented by $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ in which the required values can be filled by using the provided points as they are in the form of $(x_{1}, y_{1}) (x_{2}, y_{2})$ .

$\begin{matrix} m = \frac{- 6 - 4}{2 - (- 3)} \\ = \frac{- 10}{2 + 3} \\ = \frac{- 10}{5} \\ = - 2 \end{matrix}$

Step 3. Write the conclusion.

The obtained slope is $- 2$ . So, it is the required rate of change.
