Question 20 of 25

What is the slope of the line containing (-3, 5) and (6, −1)?
O A. -3
OB. 1
OC. -1
O D.
NIM

Answer 1

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

Explanation:

calculate the slope m using the slope formula

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

let (x₁, y₁ ) = (- 3, 5 ) and (x₂, y₂ ) = (6, - 1 )

substitute these values into the formula for m

m =
`(-1-5)/(6-(-3))` =
`(-6)/(6+3)` =
`(-6)/(9)` = -
`(2)/(3)`
