Problema Solution
there were 7288 walmart stores worldwide in 2008 and 10,408 walmart stores worldwide in 2013. write a linear equation in slope-intercept form that models growth. let x stand for the number of years after 2008 and let y stand for number of walmart stores worldwide
Answer provided by our tutors
The "slope-intercept" form of the linear equation is:
y = mx + b,
where "m" is the slope and "b" gives the y-intercept.
The y intercept is the value for x = 0, and in our case b = 7288.
The slope m = (10408 - 7288)/(2013 - 2008) that is m = 624.
The slope-intercept form that models growth is:
y = 624x + 7288.
