First you should rearrange the second formula so that y is the subject.
OpenStudy (anonymous):
well I think I already know the answer , both are parallel so I believe it is A >

rearrange the second one to the form
y = mx + b
then its easy to compare them
OpenStudy (welshfella):
-2x + 6y = 3
6y = 2x + 3
y = (1/3) x + 1/2
OpenStudy (welshfella):
so we have
y = -3x + 7
y = (1/3) x + 1/2
OpenStudy (welshfella):
so what do you think?

look at the 2 slopes ( the coefficients of x)
OpenStudy (anonymous):
i think it is parallel .
OpenStudy (welshfella):
no if they were parallel the coefficients of x would be the same
eg y = 2x + 1
is parallel to y = 2x - 3
OpenStudy (anonymous):
oh than they are perpendicular
OpenStudy (welshfella):
here we have have one with slope -3 and the other with slope 1/3

right
if one line has slope m then the line perpendicular to it has slope -1/m
OpenStudy (anonymous):
so the correct answer is B > (perpendicular)
OpenStudy (welshfella):
the relation between the 2 slopes is
m1 * m2 = -1
OpenStudy (welshfella):
B yes
OpenStudy (anonymous):
yay .
