Answer:

y = 3x - 1

Step-by-step explanation:

Given the data set: (1, 2) (2, 5) and (3, 8), you first need to look for a constant difference in the values of x and y:

x: 1   2   3  (add '1' each time)

y: 2  5  8  (add '3' each time)

Rate of change (slope) can be found by dividing y/x:

3/1  = 3

Since y = 2 when x = 1, then y = -1 when x = 0.  

Using slope-intercept formula: y mx + b

y = 3x - 1

So...

0=4-2x

x=2
