Jamilla collected data comparing the weight and cost of pieces of sterling silver jewelry. her data is listed as (weight in ounces, cost in dollars): (5, 44.00), (8.5, 78.50), (12, 112.00), (10, 93.00), (7, 63.50), (9, 83.20).

a. plot the data on a set of axes.
b. use a ruler to draw a line that best approximates the data.
c. determine the equation of the line of best fit drawn in (b).
d. use your equation to predict the cost of a 50-ounce silver bracelet.

need more info

step-by-step explanation:

yes the data was not prsented

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.

good luck on ur quiz test or homework. have a good day : )
