What is the rule for this table ? (need an answer urgently)

y = 1/3x -1

Step-by-step explanation:

We have 2 points  (9,2)  and (42,13)

We can find the slope

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

   = (13-2)/(42-9)

  =11/33

  =1/3

The slope is 1/3

We can use the point slope form of the equation

y-y1 = m(x-x1)

y-2 = 1/3(x-9)

Distribute

y-2 = 1/3x -3

Add 2 to each side

y-2+2 = 1/3 x-3+2

y = 1/3x -1

the answer is the third / last answer

step-by-step explanation:

its 50 miles away from the starting point
