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 »

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 »

In algebra, the point-slope form of an equation for a line is written as y - y1 = m(x - x1). The variables y1 and x1 equal the values of the given point, and m equals the slope. 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 »

There is no true solution to x2+y2= 25, but it can be converted to slope intercept form by solving for y. To solve for y, x2 should be subtracted on the right side making the equation y2 = -x2 + 25. It can then be divide... More »
