6.
A student suggests that the graph represents the inverse variation y = 3/x. Is the student correct? Why or why not?
a)
Yes, because the points get smaller from left to right.
b)
Yes, because the points prove the constant of variation is 3.
c)
No, because the points prove the constant of variation is 6.
d)
No, an inverse variation graph is a straight line with a positive slope.
