Step-by-step explanation:
Line 1:
y = -3/4x - 7
Line 2:
8x - 6y = 2
-6y = -8x + 2
y = -8/-6x - 2/6
y = 4/3x - 1/3
Lines 1 and 2 are perpendicular because the slopes are reciprocals.
Line 1:
y = -3/4x - 7
Line 3:
4y = -3x + 3
y = -3/4x + 3/4
Lines 1 and 3 are parallel because the slope is the same, but their y-intercepts are different.
Lines 2 and 3 are perpendicular because the slopes are reciprocals.
