hint:
we have a direct variation, when we can write:
y=k*x
OpenStudy (michele_laino):
namely, the ratio:
y/x, is constant for all pairs (x,y) in your tables
OpenStudy (michele_laino):
for example, using the data of the table 2, we have:
3/1.5=2
12/8=3/2=1.5
so 3/1.5 is not equal to 12/8

using the data of your first table, we get:
7.5/3=...?
11.25/4.5=...?
17.5/7=...?
please complete
OpenStudy (popstar30977):
why are they all 2.5
OpenStudy (popstar30977):
they are both the same right
OpenStudy (michele_laino):
yes!
that is the meaning of direct variation
OpenStudy (michele_laino):
all three ratios are equal to 2.5
