Calculate the formula of a line parallel to another line. Enter the slope-intercept form of the first equation, and a coordinate point the second line passes through to calculate the equation of the second line.

## Parallel Line Formula

The following formulas are used to calculate a parallel line.

m1 = m2

- Where m1 is the slope of the first line
- m2 is the slope of the second line

b = y2-m2*x2

- Where b is the y-intercept in the parallel line
- y2 is any y coordinate on the parallel line
- X2 is any x coordinate on the parallel line

## Parallel Line Definition

A parallel line is defined as any line that has the same slope as the original line.

## How to calculate a parallel line?

How to calculate a parallel line?

**First, determine the slope of the original line.**Measure or calculate the slope of the original line.

**Next, determine a coordinate point along a parallel line.**In theory, this could be any point in space, but usually, it is given in the problem.

**Finally, calculate the equations of the parallel line.**Using the formulas above, determine the parallel lines slope and y-intercept to come up with an equation.
