Question 53856: 1.) Sales last month were 4000.00, this month they were 5000.00. Write an equation that shows this using y for sales and x for the month. (this month x=0, last month x=-1, next month x=1 etc... 2.) What will the sales be 4 months from now?
Can someone show me how to work this? Thanks.

You can put this solution on YOUR website! 1.) Sales last month were 4000.00, this month they were 5000.00. Write an equation that shows this using y for sales and x for the month. (this month x=0, last month x=-1, next month x=1 etc... 2.) What will the sales be 4 months from now?
---------------
You have two points: (-1,4000),(0,5000)
slope = [5000-4000]/[0-(-1)]
slope = 1000
The y-intercept is 5000 as you see in the point (0,5000)
EQUATION:
Sales=1000x+5000
---------
4 months from now means x=4
Sales = 1000(4)+4000
Sales = $8000
