![]() ![]() 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. You can check our average rate of change calculator to find the relation between the variables of non-linear functions. Or you can also graph two linear equations and find the intersection of two lines, if it exists.In this slope intercept calculator, we will focus only on the straight line. Often times, you just want to have a quick look at how things look graphically, for which you could use this tool for Other useful calculators related to linear functions Example: Calculation of the equation of a lineĪssume that you have a line that passes through the point \(\left( \frac\). In order to see an example of how this calculator deals with fractional linear equations, check the example below. Generic numeric expression, which includes fractions. One of the neat things about this calculator is that all the coefficients you use to define the equation can be any Can this solver deal with fractional linear equations? Why is the standard form neededĬertain specific forms of an equation come from tradition, but usually because it is useful to use a specific form.įorm, it is practical to have it in the form \(a x by = c\), because by plugging \(x=0\) it is easy to compute theīy plugging \(y=0\) it is easy to compute the x-intercept.Īlso, the standard form is commonly used as the format of choice when solving simultaneous With this calculator, all you have to do is provide information to define the equation, among the four different options. How do you solve standard form on a calculator? ![]() Then, your goal is to determine the standard form formula and find the constants a, b and c that determine it. What is the format of a linear equation in standard form?Ī linear equation is said to be in standard form if it has the following structure: What way will you use to define your equation will depend on what information you have available. Or (3) you can provide two points where the line passes through. Or (2) the slope and one point where the line passes through, For this purpose, you can either provide anĮquation directly, or otherwise, depending on the information you have available, you can provide: How to find the equation of a line? So the first thing, is to define a linear equation. This equation of the line in standard form equation calculator will allow you to define an equation in one of four ways you prefer,Īnd it will show you all of the steps required.
