Josh's Strategy
1. Found the avg. of the difference of the y-values
2.Divide by the change in the x values=slope
3. Expanded table using the slope to find the y-intercept
Emma's Strategy
1. Graphed Data
2. Graph a general line
a. connect first-last point
b. move all pts over a certain distance
3. Find the equation of general line
**Do you think there is a relationship between grams of fat and total calories in fast food?
-If there are more grams of fat, will there be more total calories?
Sandwich Type Total Fat (g) Total Calories
Hamburger 9 260
Cheeseburger 13 320
Quarter Pounder 21 420
Quarter Pounder w/cheese 30 530
Big Mac 31 560
Special Sandwich 31 550
Special Sandwich w/cheese & Bacon 34 590
Crispy Chicken 25 500
Fish Filet 28 560
Grilled Chicken 20 440
Grilled Chicken Lite 5 300
What do you notice about this data? Math observations.
*Total calories all end in 0 (might influence how you scale the graph)
*More fat, more calories (w/ this noticing, would expect linear trend)
*A lot of the foods seem to be in the 500 calorie range (scale)
*Doesn't appear to be going up by a constant rate
*Special Sandwich w/ cheese and bacon has the most fat!
*Total Fat and Total calories doesn't seem to be in any order (May need to graph this)
* Add cheese and bacon, fat and calories go up
*Big Mac and Special Sandwich have same total fat, but different calories
*There are 2 dependent variables (Total Fat, Total Calories)
*Only graphing total fat and total calories, sandwich doesn't really matter
Where am I going to graph this?
x axis: Total fat (g)
y axis: Total calories
