Question 44494
First you have to find "m" (slope) (y2-y1)/(x2-x1)

 m=314-42/17-1 =272/16 or 17 
 m=17

Then finding the equation of a line with the two points given.

  (y-y1)=m(x-x1)  or 

  (y-42)=17(x-1)
   y-42 = 17x-17
   y-42+42 = 17x-17+42
   y= 17x+25
   
  m=17   y = (0,25)

Hope this help
