Question 30603: +%282%2C1%29and%286%2Cy%29+
Suppose the ordered pairs in this exercise are for the same direct variation. They are asking me to find the missing value.
I actually thought that the missing variable was 5.

You can put this solution on YOUR website!
(2,1) and (6,y)
for a direct variation the equation is:
+k=y%2Fx+
so using the first point ...
+k+=+1%2F2+ plug this and (6, y) into the equation
+k=y%2Fx+
+1%2F2=y%2F6+ solve for y
since 2 * 3 = 6
then 1 * 3 = 3
y = 3
