Because most linear functions are given in slope-intercept form, they can be easier to work with than point-slope form. To convert, you must isolate the y variable, for which you may need a calculator. More » Math Algebra

Many linear equations are given in slope-intercept form (y = mx + b), and sometimes they must be converted to standard form (Ax + By = C). Converting slope-intercept to standard form is mostly a matter of converting frac... More »

A slope intercept calculator is a tool used to determine the slope-intercept form of an equation for a line passing through two points on a Cartesian coordinates plane. Other uses include calculation of the slope itself ... More »

To find the equation of a line given the slope and a single point, you need to use the point-slope form of y - y1 = m(x - x1). It is almost identical to the slope-intercept form, but you have to find the point for the y-... More »

To find the slope of the tangent line to the graph of a function at a point, find the derivative of the function, then plug in the x-value of the point. Completing the calculation takes just a few minutes by hand, or a c... More »

Percent slope can be converted to degrees by simply taking the arctan, or the inverse of the tangent function, of one-hundredth of the percent slope. Mathematically, the conversion formula is written as: degrees = arctan... More »

The slope-intercept form of the equation of a line is y = mx + b, where m is the slope of the line and b is the y intercept. To solve for y, multiply the x value by the slope, then add the y-intercept. To solve for x, su... More » Math Algebra
