Answer: To find the equation for Jackie's salary, we can use the fact that it is proportional to the number of hours she works. Let s be her salary and h be the number of hours she works, then we have:
s = kh
where k is the proportionality constant. To find k, we can use the given information that she made $49 in 7 hours:
49 = k * 7
k = 7
So the equation for Jackie's salary is:
s = 7h
To graph this equation, we can plot points that satisfy it. For example, when h=1, s=7; when h=2, s=14; and so on. We can also notice that the graph is a straight line passing through the origin (0,0), with a slope of 7/1 = 7.
Therefore, the graph that best models the relationship between the number of hours Jackie works and her salary is a straight line passing through the origin with a slope of 7.
