Answer :
The line of best fit
[tex]y=900x+39750[/tex]Represents the relationship between his annual salary "y" with respect to the years "x"
The y-intercept of the line represents the value of y when x equals zero.
For this example, it represents Jamal's annual salary during his first year.
Following the slope-intercept form:
[tex]y=mx+b[/tex]The y-intercept is represented by "b", and is the constant of the line.
The correct answer is: b=39750; Jamal expects to earn $36,750 during his first year.
