Hi, To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx
Here: X=25 Y=160 160=k25 (Divide both sides by 25 to isolate K) K=6.5
Then plug K value into equation Y=6.5X
Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.
