A boat is worth $10,000 when it is 5 years old and $4,000 when it is 8 years old. What is the point slope form of the line?
y - 4,000 = 2,000(x - 10,000) or
y - 10,000 = -2,000(X - 5)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
