(-17,8)
(3,-2)
y-y1=m(x-x1)
where a point is (x1,y1)
and slope=m
slope of 2 points
(x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-17,8) and (3,-2)
(x,y)
slope=(-2-8)/(3-(-17))=-10/(3+17)=-10/20=-1/2
y-y1=-1/2(x-y2)
can be
y-8=-1/2(x+17) or
y+2=-1/2(x-3)
2nd option is the answer
12÷5=2.4
2.4 minutes per watch together
so it takes john about 0.4 seconds to assemble a watch alone
Answer:
- 978.6 gallons per hour
Step-by-step explanation:
Given that :
Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal
Time during which change occurred : 2:00 pm to 4:00 pm
Average change per hour : [Change in gallon of gasoline / time interval (hour)]
Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons
Time interval = 4:00 pm - 2:00 pm = 2 hours
Hence, Average change per hour :
-1957.2 / 2
= - 978.6 gallons per hour
