$(- 2, 9)$

Step 1

To find the $\tan (θ)$ between the x-axis and the line between the points $(0, 0)$ and $(- 2, 9)$ , draw the triangle between the three points $(0, 0)$ , $(- 2, 0)$ , and $(- 2, 9)$ .

Opposite : $9$

Adjacent : $- 2$

Step 2

$\tan (θ) = \frac{Opposite}{Adjacent}$ therefore $\tan (θ) = \frac{9}{- 2}$ .

$\frac{9}{- 2}$

Step 3

Move the negative in front of the fraction.

$\tan (θ) = - \frac{9}{2}$

Step 4

Approximate the result.

$\tan (θ) = - \frac{9}{2} \approx - 4.5$
