  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 4/2 = 2.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 4/-1 = -4.
  • Slope is -2/-1 = 2.
  • Equation in slope-intercept form: y=2*x+-4.

  • X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 3/2 = 1.5.
  • Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 3/-1 = -3.
  • Slope is -2/-1 = 2.
  • Equation in slope-intercept form: y=2*x+-3.
