The Aust Corporation has gathered the following data on its copy machine costs for the first eight months of the year. Month Number of Copies Total Copy Cost January 40,000 $ 3,500 February 35,000 $ 3,200 March 60,000 $ 4,100 April 80,000 $ 5,100 May 85,000 $ 5,600 June 75,000 $ 4,800 July 82,000 $ 5,300 August 105,000 $ 6,000

Assuming the line intersects the y-axis at $2,000 and using the January activity levels what is the equation of the line that would be drawn for a scattergraph?

If we use the data of january then the quation of line is

y=mx+c

3500=40000m+2000

3500 is the value on Y axis, 40000 is the value on x axis, m is the slope of the line, 2000 is the Y intersect

the slope of the line will be 3/80 or 0.0375 and this tells the line is positive sloping.
