The michigan veteran population in 1990 was 14.2% and in 2000 was 12.4%. a) let y represent the percent of michiganders who were veterans and x represent the years since 1990. find a linear model of this situation, rounding to two decimal places.

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

it is a function because for every x value there is only one y value

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
