The slope of the given line is ∆y/∆x = (4-6)/(5-1) = -2/4 = -1/2. The slope of the desired (perpendicular) line is the negative reciprocal of this, -1/(-1/2) = 2.
The point-slope form of the equation for a line with slope m through point (h, k) is
... y - k = m(x - h)
For slope 2 and the given point, your equation can be
... y + 6 = 2(x + 2)
The bag with 40 candies has 10 orange ones
bag with 60 pieces has 6 orange ones
1min: 100 ft
2min: 100(.5)= 50 ---> 100+50= 150 ft
3min: 50(.5)=25 ---> 150+25= 175 ft
4min: 25(.5)=12.5 ---> 175+12.5= 187.5 ft
5min: 12.5(.5)=6.25 ---> 187.5+6.25= 193.75ft
answer: 193.75 ft
I think that can help for now
