Slope of Line from a Graph by Rise over Run, by slope formula, and by equation of line
Day2 Intermediate Algebra Part 1:
In this video, we start by practicing graph a line by plotting intercepts, and then we introduce the three methods for finding slope:
The slope between two points using the formula m = (y2-y1)/(x2-x1).
The slope from a graph by rise over run.
The slope from an equation of a line using the slope-intercept form: y=mx+b.
This is part 1, in which we practice the rise over run technique. Watch the other parts to see the other techniques.
