Question

snack accounts
the equation for the line of best fit is ( y = - 3x + 37 ). according to the equation, which of these statements is true?
after 3 days, a kid would probably have about $37 in their snack account.
kids typically start with about $37 in their snack accounts.

Explanation:

Step1: Analyze the linear equation

The equation of the line of best fit is \(y = - 3x+37\), where \(y\) is the account balance and \(x\) is the number of days since camp started.

Step2: Evaluate the \(y -\)intercept

In the linear equation \(y=mx + b\) (slope - intercept form), \(b\) is the \(y -\)intercept. When \(x = 0\) (the start of camp, i.e., day \(0\)), \(y=-3\times0 + 37=37\).

Answer:

Kids typically start with about \(\$37\) in their snack accounts.
