Answer
These two lines are perpendicular. The slope of the second is the negative reciprocal of the slope of the first.
Work Step by Step
$y=\frac{2}{3}x+1$
$2y+3x=1$
$y=-\frac{3}{2}x-\frac{1}{2}$
These two lines are perpendicular. The slope of the second is the negative reciprocal of the slope of the first.
