Answer:  the second option is correct  
Using Slope = rise/run .  
 
You can create a graph to see the intercepts (attached) OR
Step-by-step explanation:  
To find the y-intercept, figure half way between (-1, -2) and (1, 2/3) 
  Half of that is 
  below the origin, y-intercept is 
 or 
to create an equation for this:
Take the difference in y-values  
  
which simplifies to 4 for the Rise
Take the difference in x-values  
so the Run is 6
The slope is the slope is 4/6 , the same as 2/3.
Use slope intercept form to create the equation:

You can compute the x-intercept by substituting 0 for y
0 = 2x/3 - 4/3 .   4/3 = 2x/3   multiply both sides by 3 
4 = 2x   divies both sides by 2  to get  2 = x, the x-intercept
