Question

Find the slope of the line that goes through (7,1) and (2,11)

Answer 1

slope = - 2

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (7, 1 ) and (x₂, y₂ ) = (2, 11 )

substitute these values into the formula for m

m =
`(11-1)/(2-7)` =
`(10)/(-5)` = - 2
