Tell whether the lines for the pair of equations are parallel, perpandicular, or neither.

Y=-2/3x+1
2x-3y=-3

Question

Tell whether the lines for the pair of equations are parallel, perpandicular, or neither. 

Y=-2/3x+1
2x-3y=-3

anonymous · Answer

-3y = -2x-3

y = 2/3x+1
y= -2/3x+1 

y = mx+b
m is the slope 
so 
parallel when the two equations have the same slope 
perpendicular when the slope of the equations are reciprocal with one another and have different sign

anonymous · Answer

So perpendicular? :) @helpme1.2

anonymous · Answer

example of perpendicular slope; 
if the first slope was 5/6 its perpendicular would be -6/5

anonymous · Answer

what do you notice about the 2 slopes for your problem

anonymous · Answer

they are the same! so they are parallel!? @helpme1.2

anonymous · Answer

one of them is negative and the one one is positive 
-2/3  not equal to 2/3

anonymous · Answer

so they are not the same meaning they are perpendicular? @helpme1.2

anonymous · Answer

-2/3 perpendicular would be 3/2
you forgot the other option
Neither
