Question

What is the x-intercept of the line with this equation -3x+1/2y=18

Answer 1

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
• 
  `(-3x+1)/(2y)(2y) =18(2y)\\-3x+1=36y\\y=(-3x+1)/(36)`
• Now plug in y=0
• 0=-3x+1
• -3x=-1
• 
  `x=(1)/(3)`
