Chapter 1: Q. 11 (page 40)

In problems $11 - 14, (a)$ find the slope of the line and $(b)$ intercept the slope.

Short Answer

Expert verified

(a) The slope of the line is $m = \frac{1}{2}$ .

(b) The line makes an angle $t a n^{- 1} (\frac{1}{2})$ with the positive $x -$ axis.

Step by step solution

Step 1. Given information.

We have:

Part (a). Step 1. Find slope.

Two are are given in given graph:

$(0, 0)$ and $(2, 1)$

Slope between two points: $Slope = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$(x_{1}, y_{1}) = (0, 0), (x_{2}, y_{2}) = (2, 1) m = \frac{1 - 0}{2 - 0} m = \frac{1}{2}$

Part (b). Step 1. Intercept the slope.

Slope of the line is given by:

$m = \tan θ \frac{1}{2} = \tan θ θ = \tan^{- 1} (- \frac{1}{2})$

Therefore, the line makes am angle $\tan^{- 1} (\frac{1}{2})$ with positive $x -$ axis.
