O A y=-2x
O B. y= **
O C. y= 2x
O D. y=-7x
O E y=7x
OF. y= x

F

Step-by-step explanation:

This is a constant of proportionality graph which means y=kx  where k is the slope or rate of change. TO write an equation for the graph will just need to find K .

y=kx  solve for x  by divide both sides by x

k = y/x  

So we know that one the line there is a located point (7,2)  and to solve for k we need to divide the y value by the x.

k=2/7

y= 2/7x
