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 = (y_2 - y_1 )/(x_2-x_1) }`

where,

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

lets solve,

• 
  `\hookrightarrow ( - 10 - ( - 8))/( - 9 - 1)`

• 
  `\hookrightarrow ( - 2)/( - 10)`

• 
  `\hookrightarrow (1)/(5)`
