Learn about the slope-intercept form of two-variable linear equations, and how to interpret it to find the slope and y-intercept of their line. read more
The Formula. In general, the slope intercept form assumes the formula: y = mx + b. m is the slope (lesson on slope ) mnemonic : 'm' means 'move' b is the y -intercept ( lesson on the y-intercept) mnemonic : 'b' means where the line begins. read more
This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.) I like slope-intercept form the best. read more
