Answer:
A and B
Step-by-step explanation:
we have:
A: 2x-3y=6
-3y=-2x+6
3y=2x-6
y=2x-6/3
y=2/3x-2
so the slope here is 2/3
B: 3x-2y=-9
-2y=-3x-9
2y=3x+9
y=3/2x+9/2
so the slope here is 3/2
in C the slope is -32 and in D it's 23
perpendicular lines can be known using the rule:
slope (first line)=-1/slope (second line)
2/3= -1 over 3/2
so A and B are the two perpendicular lines
