This section covered slopes, slope formulas, slope relationships, slope-intercept form, and some review on parallel and perpendicular lines.
slope the ratio of a line's vertical rise to it's horizontal run
rate of change how much a quantity changes over time
The slope of parallel lines are always equal
The slope of perpendicular lines always are opposite reciprocals.
Skew Lines that are not coplanar and do not intersect at any point.
Slope-Intercept Form y=mx=b
point-slope form y-y1=m(x-x1)
