A millennium is 1000 years.
Multiply the number of seconds in 1 year by 1000:
31,536,000 x 1,000 = 31,536,000,000 seconds.
20.136 rounded to nearest whole number is 20
(5,-3) (-1,6)
y=mx+b
calculate m:
(-3-6)/(5-(-1)
=-9/6=-1.5
y=-1.5x+b
insert the (5, -3) point to calculate b:
-3=-1.5*5+b
-3=-7.5+b
4.5=b
b=the y intercept, so the line intercepts x=0 at y=4.5
