Hello there! I can help you! So in this question, we are talking about an elephant eating 400 pounds each day. Knowing this can help us solve these questions:
a. So v represents number of pounds and d represents the number of days. We would write the equation as v = 400d, because you multiply the amount of days and pounds eaten per day to find the total amount of vegetation the animal has ate.
b. So given the equation, all we have to do is plug in a number for d and multiply to find v. Let's find the value for 3 days, starting with day 1. 400 * 1 is 400. 400 pounds eaten in day 1. 2 * 400 is 800. 800 total pounds eaten on day 2. 3 * 400 is 1,200. 1,200 total pounds eaten on day 3. With those numbers, your table should look like the one below if you do it correctly.
c. With that, your points should be placed at (1, 200), (2, 800), (3, 1,200). You can see that the line is constant, and that when you connect the dots, the line is straight. It is a linear equation, where the line is straight and the value is constant.
