The points are (1999,45) and (2009,59)

Answer:
Slope = 1.4
Step-by-step explanation:
So the slope is the rate of change and the formula is:
[tex]\frac{y_{1} - y_{2} }{x_{1} -x_{2} }[/tex]
So y^2 is 59
y^1 is 45
x^2 is 2009
x^1 is 1999
[tex]\frac{59-45}{2009-1999}[/tex] = [tex]\frac{14}{10}[/tex] = 1.4
The slope = 1.4
