Determines the equation of a line (in slope-intercept or standard form) given two points on the line.
Start with your values, or try a preset.
Enter x-coordinate of Point 1, y-coordinate of Point 1, x-coordinate of Point 2, and y-coordinate of Point 2 in the units shown.
Read Standard Form: Ax + By = C (B), Slope (m), Standard Form: Ax + By = C (C), Standard Form: Ax + By = C (A), y-intercept (b), Standard Form: Ax + By = C, and Slope-Intercept Form: y = mx + b in the results panel. Results update as you change the inputs.
Choose a preset to load an example, then adjust the values for your situation.
See the inputs and their calculated results.
