To bill customers for water usage, one city converts the number of gallons used into units. this relationship is represented by the equation g = 748u, where g is the total number of gallons of water used and u is the number of units. determine which statements about the relationship are true. select two options. g is the dependent variable. u is the dependent variable. g is the independent variable. u is the independent variable. the two variables cannot be labeled as independent or dependent without a table of values. the two variables cannot be labeled as independent or dependent since any value can be selected for either.

step-by-step explanation:

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.
