Question 1148258: The average profit/loss of a company (in thousands of dollars) was documented for 30 months. The 5th month showed a loss of $3000, however the 25th month showed a profit of $9000. Assuming the profit/loss is linear, write the equation of the line, in slope-intercept form, that represents the profit/loss for each month x. Use this result to predict the profit/loss after 60 months.
Hint: Use the ordered pairs (5,-3)(25, 9).
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! slope is (9-(-3))/(25-5)
12/20=0.6
point slope formula y-y1=m(x-x1), m slope (x1, y1) point
y-9=0.6(x-25)
y=0.6x-15+9
y=0.6x-6, x months and y profit.
for 60 months, y=0.6*60-6 or 36-6=$30000 profit
