Find the slope of the line passing through the the following points: (−12, −56), (−57, 39).

Answer 1

slope of line = - 19/9

Explanation:

Point A
`(x_(1), y_(1)) = (-12, -56)`

Point B
`(x_(2), y_(2)) = (-57, 39)`

Now slope of line (m) =
`(y_(2) - y_(1) )/(x_(2) -x_(1) )`

slope of line passing through points (-12, -56) and (-57, 39) is:

=
`(39 - (-56))/(-57- (-12))`

=
`(39 + 56)/(-57 + 12)`

=
`(95)/(-45)`

=
`- (19)/(9)`
