Hope I' not too late -w-'
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of any straight line, we simply need two points off of it, so let's use the ones provided in that

let's notice, is negative since the population decreased.
The equation of line is ,
Note: 2*2 means 2 times 2
find the factors since
4/8=1/2 because 1/2 times 4/4=4/8
194=2*97
120=2*2*2*3*5
the common number is 2 so divide both by 2
97/60 is the simplest form
in improper fraction form it is
97-60=37
1 37/60
