Answer
x-intercept (3, 0), y-intercept (0, -6)
  1. Line: y = 2x - 6
  2. Y-intercept is (0, -6).
  3. Set y = 0: 0 = 2x - 6

How to use the intercepts calculator

Intercepts show where a graph crosses the axes. This calculator focuses on lines written as y = mx + b.

  1. Enter m and b.
  2. Read the y-intercept directly.
  3. Set y = 0 and solve for x.

Formula or method

For y = mx + b, the y-intercept is b and the x-intercept solves 0 = mx + b.
