Answer:

Step-by-step explanation:

  • for the x-intercept this is where the y value is equal to 0
  • But before that by inspection you can see that your equation is not in the standard form of a straight line
  • Make y the the subject of the equation
  • [tex]\frac{-3x+1}{2y}(2y) =18(2y)\\-3x+1=36y\\y=\frac{-3x+1}{36}[/tex]
  • Now plug in  y=0
  • 0=-3x+1
  • -3x=-1
  • [tex]x=\frac{1}{3}[/tex]
