In the equation of a straight line when the equation is written as y mx b the slope is the number m that is multiplied on the x and b is the y - intercept that is the point where the line crosses the vertical y -axis. The slope is the number written before the x. Slope-Intercept Form of a Line y mx b The slope-intercept is the most popular form of a straight line.
Lets look at an example.
Slope Intercept Form When a linear equation is written in slope intercept form the slope of the line can easily be identified. It also calculates the slope and the y-intercept of the line. The slope is the number written before the x. Many students find this useful because of its simplicity.
