Do the data in the table represent a direct variation or inverse variation? write an equation to model the data in the table? x 1 3 5 10 y 4 12 20 40

For this case, we observe that the table presents a direct variation.
 Therefore, we have an equation of the form:
 y = k * x
 We look for the value of k. For this, we use an ordered pair:
 (x, y) = (1, 4)
 We have then:
 4 = k * 1
 k = 4
 Thus, the equation modeling the table is:
 y = 4x
 
 An equation to model the data in the table is:
 y = 4x
