Answer:
All the answers are down here
everything in bold is the answer, but dont copy these are my original answers, and these are the answers for step 4
Step-by-step explanation:
a) Evaluate the data and find the rate of change from one age group to the next. Explain how you found the rate of change. (2 points)
To find the rate of change you will need to use the slope formula, y2 – y1 / x2 – x1. I will use points (24, 5) and (48, 10) and plug them into the equation. Then you get 10 – 5 / 48 – 24. After simplifying you would get the rate of change, which is 5 / 24.
b) Is the relationship between weight and the amount of medicine linear? Explain. (2 points)
The relationship between the weight and medicine is linear because if you graphed the line it would go through the origin. For every weight of a child there are different amounts of medicine, so the graph should start at (0, 0). The linear function for this graph is “y = 5/24x”, and since there is no y-intercept (b) it is linear. It would not make sense if the graph had a y-intercept less or greater than 0. That would mean that if a child weighed 0 pounds, they’d need medicine, and that is not possible.
