the line y=+%283%2F4%29x%2B2 has a slope m=3%2F4
by definition, perpendicular lines' slope are negative reciprocals
a line is perpendicular to the line y=%283%2F4%29x%2B2 has a slope m%5Bp%5D=-1%2Fm
m%5Bp%5D=-1%2Fm ...plug in m=3%2F4
m%5Bp%5D=-1%2F%283%2F4%29
m%5Bp%5D=-4%2F3
so, perpendicular line is y=+-%284%2F3%29x%2B2
