Question

Do the paired points in the table represent a proportional relationship on the graph?

x 2 4 6 8
y 1 2 3 4

Select the appropriate response from the drop-down menu.
1.Yes, the points represent a proportional relationship
2.No, the points do not represent a proportional relationship

Answer 1

ok so first n a graph y is over x so it would be 1/2 2/4 3/6 and 4/8 which can all be divided to 1/2 so yes they are proportional

Answer 2

If we find the unit rate for the graph, that means it's proportional. For the first question, we could see that the unit rate is 2/1, so it's proportional.
