Chicago has a population of about 2,715,000. Its territory can be modeled as a parallelogram, as shown in the figure. Each unit on the coordinate grid represents one mile. Find the approximate population density of Chicago. Round to the nearest hundred if necessary. The population density is approximately _ persons/mi2
.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
