You just have to multiply and add it is simple
Slope = (y2 - y1) / (x2 - x1)
slope = (-7-10) / (5 - (-3)
slope is supposed to be -17/8
I am guessing she made her mistake by adding a negative sign...the student did : (-7 - (-10) / (5 - (-3) = (-7 + 10) / (5 + 3) = 3/8
Answer:
(2,9)
Step-by-step explanation:
X midpoint:9+(-5)/2 which gives 2
Y midpoint:3+15/2 which gives 9
A. The persons weight decreases by 167lbs
B. 83.5%
9C5 = 9!/[5!(9-5)!
9C5 = 9!/(5!)(4!)
You finish.
7P4 = 7!/(7-4)!
7P4 = 7!/3!
You finish.
