PLEASE HELP me with this? :)
Assume a 115pound person burns 36 calories after 12 minutes of walking and 54 calories after 18 minutes of walking.
Part 1: Use calories as the ycoordinate and minutes as the xcoordinate. 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 walking? Using complete sentences, explain how the equation, slope, or graph can help to predict calories burned.

Best ResponseYou've already chosen the best response.0We use the two point formula of straight line: \[yy1=((y2y1)\div (x2x1)) \times (x  x1)\] Substituting for y1=36, x1 = 12, y2 = 54, x2 = 18, we get the equation as: \[y=3x\] Now substitute x=35 and you will get y as the calories. \[y = 3 \times 35\]\[y = 105\]
