Parallel Line Calculator

Find the line parallel to y = mx + b that passes through a given point.

Parallel slope 2
New y-intercept -2

Formula: Same slope m; b = y₀ − m·x₀

Step-by-step with your numbers:
1. Values used:
2. Slope of original line = 2
3. Point x = 3
4. Point y = 4
5.
6. Parallel slope = 2
7. New y-intercept = -2
Did we solve your problem today?

Parallel lines share the same slope but have different y-intercepts.

The math behind it

Keep the slope m and find the new intercept from the point: b = y₀ − m·x₀.

Worked example

Parallel to y = 2x + 5 through (3, 4) → y = 2x − 2.
