4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
No, the two lines are not perpendicular.
If: 3x-7+x = 5 Then: x = 3

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
No, the two lines are not perpendicular.
The slope equals 3
