Interpolate: estimate a value between two given values
It should be used only when it makes sense to have values between given values
Ex. 5.4 people, does not make sense
Extrapolate: Estimate a value beyond a given set of values
It should be used only when it makes sense to have values beyond given values
It should be used only when it makes sense to have values between given values
Ex. 5.4 people, does not make sense
Extrapolate: Estimate a value beyond a given set of values

Equation of a straight line
The equation of a straight line is usually written this way - y = mx + b
What does it stand for ?
y = mx + b
"m" is the slope (or gradient)
"b" is the y intercept
y = how far up
x = how far along
m = slope or gradient
b = the y intercept ( where the line crosses the Y axis
How do you find m + b?
b is easy : just see where the line crosses the Y axis
m : (the slope) needs some calculation
m = change in y / Change in x
Rise over Run
Rise/run
Rise - how far up (how far up it RISES)
Run - How far long the line is
