Question

What is the slope of the line that contains the points (9,-4) and (1,-5)?O A. -B. 1C. -1D. /718

Answer 1

Answer: D. 1/8

Step-by-step explanation

The slope of the line can be calculated with:

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

where (x₁, y₁) and (x₂, y₂) are the two points given. Then:

• x₁ = 9

,

• y₁ = –4

,

• x₂ = 1

,

• y₂ = –5

Thus, replacing the values and simplifying:

`m=(-5-(-4))/(1-9)`
`m=(-5+4)/(-8)`
`m=(1)/(8)`
