Or you can also graph two linear equations and find the intersection of two lines, if it exists. This calculator will find the equation of a line (in the slope-intercept, point-slope, and general forms) given two points or the slope and one point, with. 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 The equation can be in any form as long as its linear and and you can find the slope and y-intercept. The slope and y-intercept calculator takes a linear equation and allows you to calculate the slope and y-intercept for the equation. Example: Calculation of the equation of a lineĪssume that you have a line that passes through the point \(\left( \frac\). Step 1: Enter the linear equation you want to find the slope and y-intercept for into the editor. 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. Choose any two points in the form (x, y), from the table to find the. Step 2 : Let x stand for time and y stand for temperature. Solution : Step 1 : Notice that the change in the temperature is the same for each increase of 1 hour in time. Write an equation in slope-intercept form to represent the situation.More about this equation of line in standard form calculator Write the appropriate linear equation to find the temperature at any time. The table shows the plan’s monthly cost y for a given number of included minutes x. Now, substitute m = -2 and b = 82 in slope-intercept form equation of a line.Įlizabeth’s cell phone plan lets her choose how many minutes are included each month. Slope-intercept form equation of a line : Let x stand for time and y stand for temperature.Ĭhoose any two points in the form (x, y), from the table to find the slope :įor example, let us choose (0, 82) and (1, 80).įind the y-intercept using the slope and any point from the table. Notice that the change in the temperature is the same for each increase of 1 hour in time.
