Question

For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation.

x y
3 6
6 18
8 24

Answer 1

\[y \alpha x\]
for removing variation sign we put a constant
y = kx
now u have values of x and y in table try plugging in each value if u get same value of k for each value then it varies directly

Answer 2

I get some of what ore saying but im still a bit confused

Answer 3

about which part?

Answer 4

u have y = kx equation now look first value in table y = 6,x = 3
put in equation what cvalue of x u will get?

Answer 5

Answer 6

umm no.. its not any axis it just values but yes u can plot on graph but thats not the point here.

Answer 7

oh okay :/ im just like really suckish at graphs and stuff ugh
