Summary

Enter two points or a linear equation to instantly get the slope, y-intercept, and a visual graph of the line.

How it works

  1. Choose your input mode: "Two Points" or "Equation (y = mx + b)".
  2. Enter the required values in the input fields.
  3. Click "Calculate" to compute slope, y-intercept, and line equation.
  4. Read the results — slope, y-intercept, x-intercept, and equation are all shown.
  5. The graph updates automatically to plot the line on a coordinate plane.
  6. Switch modes at any time; previous values are cleared to avoid confusion.

Use cases

  • Check homework answers for algebra and pre-calculus problems.
  • Quickly graph a line without drawing it by hand.
  • Convert two-point form to slope-intercept form for reports.
  • Verify the slope of a trend line in data analysis.
  • Teach or learn how slope and y-intercept relate visually.
  • Find where a line crosses each axis (x-intercept and y-intercept).
