Assume a 125 pound person burns 150 calories after 15 minutes of jogging and 200 calories after 20 minutes of jogging.
Part 1 : Use calories as the y-coordinate and minutes as the x-coordinate. After writing two ordered pairs, find the slope. What does the slope represent in terms of the information provided?

Part 2 : Write an equation, in slope intercept form, to represent this data.

Part 3 : How many calories will this person burn after 35 minutes of jogging? Using complete sentences, explain how the equation, slope, or graph can help to predict calories burned.

wow i wish i could find my previous answer to this question because it was very detailed, but the question itself is not too bad

anonymous · Answer

the two points are $(15,150)$ and $(20,200)$ and the slope you can just about do in your head
another 5 minutes of exercise burns another 50 calories, so the slope is $\frac{50}{5}=10$

anonymous · Answer

evidently if you do not exercise at all you burn zero calories, so the equation for the line will be a line with slope 10 and y intercept 0
do you know what this equation is?
