Question

Isaac had lots of candy. He ate the same number of pieces each day, and the amount remaining can be modeled by the equation y = -5x + 83.

what is the meaning of the slope?

What is the meaning of the y-intercept?

How many pieces will he have after 6 days?

When will he have 28 pieces?

Answer 1

1. he eats 5 per day (5 less every day)

2. he starts with 83 pieces of candy

3. 53

4. on day 11

Explanation:

1. self explanatory

2. self explanatory

3. 6*-5=-30 -30+83=53

4. put y as 28

28=-5x + 83 now solve for x

subtract 83 both sides

-55=-5x

divide -5 from both sides

11=x
