Question

the equation for the line of best fit is $y = 38x + 2$. according to the equation, which of these statements is true?
the price of a silver bracelet increases by about $38 for every additional ounce of weight.
the price of a silver bracelet increases by about $38 for every additional 2 ounces of weight.

Explanation:

The line of best fit is in the form \(y = mx + b\), where \(m\) (slope) represents the rate of change. Here, \(m = 38\), meaning for each 1-unit increase in \(x\) (weight in ounces), \(y\) (price) increases by $38. Thus the first statement is true.

Answer:

The price of a silver bracelet increases by about $38 for every additional ounce of weight.
