I used the y/2 -y/1 over x/2-x/1 formula to determine the slope of : (2,5) abd (-3,-5) My answer is -10/5 The other one I would like to confirm is: (-2,-3) and (4,-9) for which I go -6/6 3/28/2014 | Karen from Fremont, NH | 2 Answers | 0 Votes Mark favorite Subscribe Comment
Your first answer should be positive as -5 - 5 = -10 and -3 - 2 = -5 so -10/-5 = +2 Your second answer is correct as -9 - (-3) = -6 and 4 - (-2) = 6 so -6/6 = -1 3/28/2014 | Bryce R. Comment
Use this notation: x1, y1, x2, y2. The forward slash means divide. (2,5) and (-3,-5): m = (-5-5)/(-3-2) = (-10)/(-5) = +2 (-2,-3) and (4,-9): m = (-9 -(-3))/(4-(-2)) = (-6)/6 = -1 3/28/2014 | Steve S. Comment Comments Thanks! 3/28/2014 | Karen from Fremont, NH Comment
