Once the slope and y-intercept are known, linear equations are easy to decipher. An instructional video first reviews how changing the slope and y-intercept affects the graph of a line. They then watch examples involving slope-intercept form, such as graphing linear equations given in slope-intercept form, writing an equation of a line given a point and the slope, and writing an equation of a line given two points.
