Question

What is the slope of the line that goes through the points (-1,4) and (14,2)?

Answer 1

slope m = -
`(2)/(15)`

Explanation:

calculate the slope m , using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

let (x₁, y₁ ) = (- 1, 4 ) and (x₂, y₂ ) = (14, 2 )

substitute these values into the formula for m

m =
`(2-4)/(14-(-1))` =
`(-2)/(14+1)` = -
`(2)/(15)`
