Question

Find the slope of the line that passes through (8,10) and (10,7)

Answer 1

slope = -
`(3)/(2)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (8, 10 ) and (x₂, y₂ ) = (10, 7 )

m =
`(7-10)/(10-8)` =
`(-3)/(2)` = -
`(3)/(2)`
