Question

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

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,

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

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

• $\hookrightarrow \dfrac{1}{5}$

Answer 2

U have the to use the formula

y2-y1/x2-x1

that will get u the slope

-10-8 = -18
-9-1= -10

this give u 18/10 which can be simplified to 9/5

so the slope is 9/5

hope this helps!
