Answer:
this y easy use your mind
A) Look at the coordinates of the four dots:
(0,0) (150,50) (300,100) (450,150)
Divide the x's by the y's ( other than the (0,0) one:
150/50 = 3
300 / 100 = 3
450/150 = 3
The ratio is the same for all of them and the first set is (0,0) so it is a direct variation graph.
B) The constant of proportionality is the ratio found above by dividing the X values by the Y values, which is 3.
