Answer:
(0, 0)
Step-by-step explanation:
"A proportional relationship" means that one variable is a constant multiple of another variable.
Example: y = 2x. The value of y is always twice the value of x. The 2 is the "constant of proportionality." Of course, that constant is not always 2--it can be any number.
In general, proportional relationships look like the pattern [tex]y=kx[/tex] where k is some contant.
No matter what value k has, if x = 0, then y = 0, so the point (0, 0) is on the graph of any proportional relationship.
