Table of Contents: Formula; Is This Tool Helpful? The way it works is by using derivatives, linear equations, and x-intercepts: This method consists of choosing a value of x for the equation and calculating the derivative of the equation at that point. Once the x-intercept is calculated, that value of x is used to repeat the process above, a specific number of times, until we arrive at a value of y that is minimum (which means that the derivative will be 0). This tool allows us to find the equation of a line in the general form Ax + By + C = 0. An asymptote is a line (that can be expressed as a linear equation) to which the function or curve, we are talking about gets closer and closer to, but never actually crosses or touches that line. Linear equations, or straight line equations, can be quickly recognized as they have no terms with exponents in them. Solution : y = x/2 - 3. Making the Calculation. However, unlike humans, not all equations are equal. Slope Intercept to Standard Form How to convert from y = mx + b to Ax + By = C It is a common to ask to have to convert equation of line from slope intercept to standard form, as demonstrated by the pictures below. So around the point x = 0, we know that y would have a huge value, but because of how maths work it does not have a defined value for that exact point. The slope calculator updates the graph and the equation automatically when you enter new values for the points. Y 1. You can calculate it in the following way: Our slope intercept form calculator will display both the values of x-intercept and y-intercept for you. Then, the formula to find the equation of a line is y = mx + b. Formula. Before we move to our next topic, it is important to note that we have made extreme over-simplifications when talking about infinity, but we feel it is a good and fast approach for those that are not used to the concept of working with infinity in maths. First calculator finds the line equation in slope-intercept form, that is, . This is equation is shown in the image above. If we take values closer and closer to 0 (something like 0.1, then 0.001, 0.000001...) we can see that the value of y increases very rapidly. Slope Intercept Form.
