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?

Respuesta :

Answer:

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.
