Question

m = y2-Y1 X2-X1 Find the slope of the line that passes through these two points. (-1,-2) m = - (-4,-1) [?] ​

Answer 1

slope = -
`(1)/(3)`

Explanation:

calculate the slope m using the slope formula

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

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

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