x-intercept

(4, 0)

y-intercept
(0, 3)
Step-by-stepShow
  1. Set y = 0: x = C/A = 12/3 = 4
  2. Set x = 0: y = C/B = 12/4 = 3

About the Intercept Calculator

Formula

x-intercept: y = 0 · y-intercept: x = 0

Worked example

Using the values pre-filled in the calculator above:

  • Line given as: Ax + By = C
  • A = 3
  • B = 4
  • C = 12

the calculator returns:

  • x-intercept: (4, 0)
  • y-intercept: (0, 3)

Working

  1. Set y = 0: x = C/A = 12/3 = 4
  2. Set x = 0: y = C/B = 12/4 = 3
