Question

What is the slope of the line passing through the points (1,3) and (3,-1)? 2 1 0 -1 -2​

Answer 1

slope m = - 2

Explanation:

calculate the slope m , using the slope formula

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

let (x₁, y₁ ) = (1, 3 ) and (x₂, y₂ ) = (3, - 1 )

substitute these values into the formula for m

m =
`(-1-3)/(3-1)` =
`(-4)/(2)` = - 2
