What is the function of Slope and how it is applied on Point-Slope Form? The slope is usually used for calculating the steepness of the line. It is also used to calculate the direction. In algebra, the slope is used to find the graph geometrically. The slope is a concept to find the direction of any line from left to right. On the other hand, point-slope form is a way … [Read more...] about What is the function of Slope and how it is applied on Point-Slope Form?
