Buddy, the head elf, was very upset. Christmas was coming and there were
no bears. They needed 8,000!
Math Concept: Y- Intercept
• The y-intercept was (0,8,000). It represents that on day zero Santa needed 8,000 bears by Christmas. 1 2 3 4 5 6 7 8 9

Buddy had a great idea. He decided to have 50 of his elves make 20 bears per day, since there were 8 days until Christmas.
Math Concept: Slope
• The slope of the line is -1,000 since the elves will be making 1,000 bears each day. This means that each day they need 1,000 less bears. 1 2 3 4 5 6 7 8 9

Each day 1,000 bears were made, making the amount of bears they needed smaller. And the amount they had bigger making Buddy happy.
Math Concept: Slope Intercept Form
• y=mx+b• y= -1000x+8000• There are -1000 bears
per day, which is 1,000 bears less then they should have then you add 8,000 to see how many bears they have left to make.

y= -1,000+8,000
Math Concept: Point Slope Form
• y-y1=m(x-x1)• y-8,000= -1000(x-8)• The y1 is 8,000
representing the amount of bears they need, while the slope is -1,000 because they need 1,000 less bears a day. The x1 value is 8 representing 8 days until Christmas.

Then 8 days later there were 8,000 bears made. Just enough for Christmas. Santa and Buddy were very happy. So they went on a
sleigh ride.
Math Concept: X-Intercept
The x- intercept is (8,0). It represents that on day 8 there were 0 bears left to make.

So he threw them a party with hot chocolate, candy, candy canes, candy corn and syrup! Buddy had fun…
