Parallel Line Calculator

Find the equation of the line parallel to y = mx + b that passes through a given point (x, y). The new line has the same slope, different intercept.

Frequently Asked Questions

How do you write a line parallel to another line?

Use the same slope. If the reference is y equals m x plus b and you want to pass through (x naught, y naught), the new line is y equals m x plus (y naught minus m times x naught).

What makes two lines parallel?

They share the same slope and never meet (assuming distinct intercepts). Vertical lines are parallel when they share the same form x equals constant.

Parallel versus perpendicular?

Parallel lines share slope. Perpendicular lines have slopes whose product is minus one, that is, slopes are negative reciprocals of each other.
