Find equation of a line given X and Y intercept

x-intercept = 4

y-intercept = -6


    • Enter your data in the input box shown below.Then select Calculate.
  • Given data X - intercept
  • Given data Y - intercept
x + y + = 0 ; written in simpliest form
  • Formula Recall
  • y = mx + b ; Equation of a line in slope form ---- Equation 1
  • mx - y + b = 0; re-writing in the form Ax + By + C = 0 ----Equation 2
  • b = y - intercept
  • slope, m = / ; slope , m = y-intercept / -( x-intercept)
  • By direct substitution of the value of m and b in Equation 2
x + y + = 0 ; written in simpliest form
NaN means Not a Number , what it means is the calculated answer is a complex number.This calculator only allows real numbers. So when the answer is a complex number, NaN will appear. Also if you enter any letter in the input box, example letter O, NaN will also appear.
