Answer:
The attached graph shows my answer.
Step-by-step explanation:
The graph has to start at the top because the number of carrots has to decrease and the graph slants down to the right because the time has to increase. Then the situation says that he eats one carrot at a time until <u>half</u> are eaten. The graph shows the line going down until approximately half. Then he doesn't eat any more, so the line is horizontal until the end of the graph to show no change.
A direct variation equation is one that requires y varies directly as x and looks like this in equation form:

where k is the constant of variation. If we solve this for y, we have y = kx, which happens to be a linear function... a line. k here, then, serves as the slope. So what we are given as points on a direct variation function are actually points on a line. The equation for this requires that we find the slope and then rewrite the formula accordingly. First the slope:

Now we need to write the equation by using one of the points' coordinates. I picked the first point that has an x coordinate of -9 and a y coordinate of -3. Fitting those into the slope-intercept form of a line,

which simplifies to
-3 = -3 + b and b = 0. That means that the equation of direct variation is

9:00 to 3:45 = 6 hours 45 min
1 lesson = 55 min
6 lessons = 5 hours 30 min
5.3 + 0.25 = 5 hours 55 min
6.45 - 5.55 = 50 min
lunch = 50 min
