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.
In this slope intercept calculator, we will focus only on the straight line.
