This means that the x-axis will represent the time passed, and the y-axis will represent the distance to the car. Its movement can be plotted as time versus the distance the car is from you (as shown above). Imagine a car moving at a fixed speed towards you. We will start with simple ones from physics so that you can get an intuitive idea of what the y-intercept and x-intercept mean. We have already seen what is the slope intercept form, but to understand why the slope intercept form equation is so useful you should know some applications it has in the real world. You will see later, why the y-intercept is an important parameter in linear equations, and you will also learn about the physical meaning of its value in certain real-world examples. To find it, you have to substitute x = 0 in the linear equation. The y-intercept is the value of y at which the line crosses the y-axis. You can read more about it in the description of our slope calculator. If it is negative, y decreases with an increasing x. If it is positive, the values of y increase when x increases. It tells us how much y changes for a fixed change in x. The term slope is the incline, or gradient, of a line. You can use these values for linear interpolation later. This is the so-called slope intercept form because it gives you two important pieces of information: the slope m and the y-intercept b of the line. (For example, you will find an x or a y, but never an x².) Each linear equation describes a straight line, which can be expressed using the slope intercept form equation.Īs we have seen before, you can write the equation of any line in the form of y = mx + b. Linear equations, or straight line equations, can be quickly recognized as they have no terms with exponents in them.

There you can find a full description of these types of functions! You can also check our average rate of change calculator to find the relation between the variables of non-linear functions. We have two special calculators dedicated to such an equation, namely the parabola calculator and the quadratic formula calculator. 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. On the other hand, y = mx + b (with m and b representing any real numbers) is the relationship of a straight line. For example, y = x² + x is a parabola, also called a quadratic function. The specific form of will determine what kind of line we have. Any line on a flat plane can be described mathematically as a relationship between the vertical (y-axis) and horizontal (x-axis) positions of each of the points that contribute to the line.
