In 2003, the population of a certain country per square mile of land area was 87. In 2000, the person per square mile population was 84.6. Assume the relationship between years and persons per square mile is a linear relationship.
a. Write an equation, in slope-intercept form, describing the relationship between year and persons per square mile. Use ordered pairs of the form (x, y), where x is the
number of years past 2000 and y is persons per square mile.
b. Use this equation to predict the person per square mile population in 2020,

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
