Of the 210 boys in 8th grade 190 have cell phones of the 160 girls in 8th grade 152 have cell phones determine if the relationship is proportional
a. proportional
b. not proportional

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

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.
