Question

Calculate the slope of the line that passes through (-10, 3) and (2, -3

Answer 1

slope = -
`(1)/(2)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 10, 3 ) and (x₂, y₂ ) = (2, - 3 )

m =
`(-3-3)/(2-(-10))` =
`(-6)/(2+10)` =
`(-6)/(12)` = -
`(1)/(2)`
