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 >

OpenStudy (welshfella):

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?

OpenStudy (welshfella):

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

OpenStudy (welshfella):

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 .

OpenStudy (anonymous):

thank you so much have a great day i will be giving you a medal !!!! :p
