Question

An experiment was conducted that recorded the weight of a new bar of soap after each use. The line of best fit for the data collected is
y = -5.6x + 123, where y is the weight of the bar of soap, in grams, and x is the number of times that the bar was used.
Which statement describes the meaning of the y-intercept for the line of best fit equation?

Answer 1

Answer:

The initial weight of the bar soap is 123g

Step-by-step explanation:

No options but the question can still be solved.

Given

$y = -5.6x + 123$

Required

What does the y intercept mean

Start by calculating the y intercept (i.e. when x = 0)

The equation becomes

$y = -5.6*0 + 123$

$y = 0 + 123$

$y = 123$

This means that the initial weight of the bar soap is 123g
