# How to find slope with two points and write a equation

Slope-intercept form linear equations Video transcript A line goes through the points -1, 6 and 5, 4. What is the equation of the line? So that is my x axis. Intercepts and linear equations in machine learning and science The slope intercept form calculator tells you how to find the equation of a line for any two points that this line passes through.

It will help you find the coefficients of slope and y-intercept, as well as the x-intercept, using the slope intercept formulas.

Read on to learn what is the slope intercept form of a linear equation, how to find the equation of a line and the importance of the slope intercept form equation in real life. What is the slope intercept form? Any line in a flat plane can be described mathematically as a relationship between the vertical y-axis and horizontal x-axis positions of each of points that contribute to line.

The specific form of [something with x] will determine what kind of line we have. In this slope intercept calculator, we will focus only on the straight line, but those interested in knowing more about the parabolic function should not worry.

We have two special calculators dedicated to such an equation, namely the parabola calculator and the quadratic formula calculator. Everything about this type of functions is explained in detail! Linear equations, or straight line equations, can be recognized by having no terms with exponents on them.

Each linear equation describes a straight line, and can be expressed using the slope intercept form equation. This is the so-called slope intercept form, because it gives you two important pieces of information: You can use these values for linear interpolation later.

The term slope is the inclination, or gradient, of a line. It tells us how much y changes for a fixed change in x.

If it is positive, the values of y increase with increasing x. If it is negative, y decreases with an increasing x.

You can read more about it in the description of our slope calculator. You will see later, why the y-intercept is an important parameter in linear equations and you also learn about the physical meaning of its value in certain real-world examples. Slope intercept formula derivation How to find the slope intercept form of a linear equation, then? We will assume you know two points that the straight line goes through. Your unknowns are the slope m and the y-intercept b. Firstly, substitute the coordinates of the two points into the slope intercept equation: This slope intercept form calculator allows you to find the equation of a line in the slope intercept form.

All you have to give are two points that the line goes through. You need to follow the procedure outlined below. Write down the coordinates of the first point. Write down the coordinates of the second point as well. Use the slope intercept formula to find the slope: You can also use the distance calculator to find the distance between the two points.

Find the x-intercept and y-intercept There is also always a possibility to find the x-intercept of the line. It is the value of x at which the straight line crosses the x-axis it means the value of x for which y equals 0.

You can calculate it in the following way: Real world uses of y-intercept and x-intercept We have already seen what is the slope intercept form, but to understand why the slope intercept form equation is so useful to know what kind of applications it can have in the real world, let's see a couple of examples.

Let us start with simple ones from physics so that you can get an intuitive idea of what the y-intercept and x-intercept mean. Imagine you have a car moving at a certain speed. This movement can be plotted as the time versus the distance from the car to you as shown above.

This means that the x-axis will represent the time passed and the y-axis will represent the distance to the car. You can even imagine the car has started to move before you started the timer that is: And so, the value of y will indicate the starting position distance of the car with respect to you.

This value is, like we have discussed before, the same as the value of b in the slope intercept form of a straight line equation. Then the value of x at this point will be the time when you and the car were at the same place.

Let's hope that means you were inside the car, and not under.The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

If you know two points that a line passes through, this page will show you how to find the equation of the line. Fill in one of the points that the line passes through.

Let's assume it is a point with x₁ = 1 and y₁ = 1. Write down the coordinates of the second point as well.

Let's take a point with x₂ = 2 and y₂ = 3. Use the slope intercept formula to find the slope: m = (y₂ - y₁)/(x₂ - x₁) = ()/() = 2/1 = 2.
