Answer:

6

Step-by-step explanation:

The constant of variation is the slope

k = (y2-y1)/(x2-x1)

  = (30-18)/(5-3)

   =12/2

   = 6

Answer:

y = 6x

Step-by-step explanation:

Note that 18 is 6 times 3 and that 30 is 6 times 5.  This is a sure giveaway that the constant of variation, k, is 6.

Thus the equation representing this line is

y = 6x
