Question

The michigan veteran population in 1990 was 14.2% and in 2000 was 12.4%.

Answer 1

Since we are given two ordered pairs or points, therefore we can use the point-slope formula to create the linear model.

 

The general equation is in the form of:

y = mx + b

where m is the slope and b is the y-intercept

 

The slope can be calculated as:

m = (y2 – y1) / (x2 – x1)

m = (12.4 – 14.2) / (2000 – 1990)

m = -0.18

 

SO:

y = -0.18x + b

 

Choosing any ordered pair to calculate for b:

12.4 = -0.18(2000) + b

b = 372.4

 

Hence,

y = -0.18x + 372.4
