The points (6, -3) and (14, r) lle on a line with slope 1/2
Find the missing coordinate r.

r = 1

Step-by-step explanation:

(6, -3) ; (14, r)

Slope =

Cross multiply,

(r + 3)*2 = 1*8

2r + 6  = 8             {Subtract 6 from both sides }

       2r = 8 - 6

       2r = 2          {divide both sides by 2}

        r = 2/2

r = 1

think about it deeply and passionately about this property

i am sorry
