Question

Find the slope of the line through the points (1,−8) and (−9,−10).

You may have to simplify your answer to match one of the choices.

Answer 1

Here's the solution :

we know,

$\boxed{slope = \frac{y_2 - y_1 }{x_2-x_1} }$

where,

• $y_2 = -10$
• $y_1 = -8$
• $x_2 = -9$
• $x_1 = 1$

lets solve,

• $\hookrightarrow \dfrac{ - 10 - ( - 8)}{ - 9 - 1}$

• $\hookrightarrow \dfrac{ - 2}{ - 10}$

• $\hookrightarrow \dfrac{1}{5}$
