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?


Sagot :

Answer:

The initial weight of the bar soap is 123g

Step-by-step explanation:

No options but the question can still be solved.

Given

[tex]y = -5.6x + 123[/tex]

Required

What does the y intercept mean

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

The equation becomes

[tex]y = -5.6*0 + 123[/tex]

[tex]y = 0 + 123[/tex]

[tex]y = 123[/tex]

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