Assume a 150 pound person burns 120 calories after 2 hours of sleep and 240 calories after 4 hours of sleep.
Part 1 (2 points): Use calories as the y-coordinate and hours 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 (2 points): Write an equation, in slope intercept form, to represent this data.

Part 3 (2 points): How many calories will this person burn after 8 hours of sleep? Using complete sentences, explain how the equation, slope, or graph can help to predict calories burned.#

slope = 60 pound burns/h
equation , y =60x
480 burns after 8 hours of sleep

anonymous · Answer

Thanks! That really helped. But can you explain how you get that.

anonymous · Answer

well , make the ordered pair like (2,120) and (4,240)
formula : slope = change in ordinate/change in abcissa
foumula : slope intercept form Y-Y1 =m(X-X1)         m : slope
you will find the equation and then you put hour 8 and find 480.
