# How do you find the slope of parallel lines?

## How do you find the slope of parallel lines?

Explanation: First, you should put the equation in slope intercept form (y = mx + b), where m is the slope. The slope of the line is -3/8. A parallel line will have the same slope, thus -3/8 is the correct answer.

### What is the formula for parallel lines?

In a linear equation of the form y=mx+b, parallel lines will always have the same m. Practice writing parallel equations given different pieces of information.

**What is an example of parallel slopes?**

For example, observe the purple line and the green line in Figure 1 below. These lines are parallel and have the same slope of m=3/5.

**What is a parallel slope?**

Note that two lines are parallel if their slopes are equal and they have different y-intercepts. Perpendicular Lines and Their Slopes. In other words, perpendicular slopes are negative reciprocals of each other. Here is a quick review of the slope/intercept form of a line.

## How do you find the slope of a line parallel to two points?

When given two points, (x 1, y 1) and (x 2, y 2), on a line, we can calculate the slope of the line using the formula (y 2 – y 1) / (x 2 – x 1). Because parallel lines run in the same direction, they have the same slope.

### How do you find the slope of a parallel line?

Slope. y2 – y1/x2 – x1 = slope.

**What does the slope of a parallel line Tell You?**

The slope indicates the steepness of a line and the intercept indicates the location where it intersects an axis. The slope and the intercept define the linear relationship between two variables, and can be used to estimate an average rate of change.

**Are two lines that have the same slope parallel?**

Lines in a plane that are parallel, do not intersect. Two lines are parallel if they have the same slope, or if they are vertical. If two parallel lines form a system, there are no solutions to the system. If lines intersect, the lines cross in one point.

## What are types of slope do parallel lines have?

Parallel lines have the same slope. Parallel lines continue,literally,forever without touching (assuming that these lines are on the same plane).
