Are the pairs of lines parallel, perpendicular , or intersecting?
y = -2/3x + 7
-2x -3y = 12
y - 6 = 1/4(x + 2)
y = -4x -10
2x - y = 7
3x - 4y = -8
The pairs of lines are as follows:
1. y = -2/3x + 7 and -2x -3y = 12
These lines are intersecting.
2. y - 6 = 1/4(x + 2) and y = -4x -10
These lines are perpendicular.
3. 2x - y = 7 and 3x - 4y = -8
These lines are intersecting.
