This calculator finds the equation of a line parallel to a given line and passing through a specified point. It uses the slope-intercept form (y = mx + b).
Start with your values, or try a preset.
Enter Slope (m) of the original line, Y-intercept (b) of the original line, X-coordinate of the point the parallel line passes through, and Y-coordinate of the point the parallel line passes through in the units shown.
Read Slope (m) of the parallel line, Y-intercept (b) of the parallel line, and Equation of the parallel line (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.
Slope (m) of the original line: 2; Y-intercept (b) of the original line: 3; X-coordinate of the point the parallel line passes through: 1; Y-coordinate of the point the parallel line passes through: 5
Slope (m) of the parallel line: 2; Y-intercept (b) of the parallel line: 3; Equation of the parallel line (y = mx + b): y = 2x + 3
Slope (m) of the original line: -1; Y-intercept (b) of the original line: 0; X-coordinate of the point the parallel line passes through: 2; Y-coordinate of the point the parallel line passes through: 1
Slope (m) of the parallel line: -1; Y-intercept (b) of the parallel line: 3; Equation of the parallel line (y = mx + b): y = -1x + 3
