Question

How to graph 14x+18y=126

Answer 1

• We need to rearrange this into
  `y=my+c`
• Subtract 14x from both sides
• 
  `18y=-14x+126`
• Divide both sides by 2
• 
  `9y=-7x+63`
• Divide both sides by 9
• 
  `y=(-7x+63)/(9)=(-7x)/(9) +(63)/(9)`
• Plot the point (0, 63/9)
• Then pick some x values and put them into the equation to find the respective y values
• Then plot those points
• Finally join up those points
