Two lines that are parallel to each other have the same rate of
change (or slope). two lines that are perpendicular to each other have slopes
that are opposite reciprocals. for example, if line a and line b are
perpendicular to each other, line a could have a slope of -- and line b could
have a slope of 10
now suppose line c passes through the points (18,48) and (-27,-28). line
d passes through the point (27, 15) and is parallel to line c. line e passes
through the point (-1,-3) and is perpendicular to line c. what are the
equations in slope-intercept form of lines c, d, and e? (all equations should
contain either integers or simplified fractions.)
the equation of line c is
the equation of line d is
the equation of line eis
