Parallel line calculator
Find a line parallel to a given line passing through a specific point. Parallel lines have the same slope.
Parallel to slope m =
Through point (x, y)
Parallel lines
Two lines are parallel if they have the same slope. If line 1 has slope m, any parallel line also has slope m.
Parallel to y = 2x + 1 through (1, 3): slope = 2, so y − 3 = 2(x − 1) → y = 2x + 1.
