Question

Select the pair of equations whose graphs are perpendicular.	    A. y = 2x – 7 x + 3y = 3    B. 2y = –3x + 5 2x – 3y = 4    C. 3x + 6y = 8 y = 3x – 8    D. 5x – 8y = 9 12x – 5y = 7

shamim · Answer

ur given equations r overlapping

usukidoll · Answer

for real? dude graph each pair in separate graphs and see which one is perpendicular... there should be one point where both lines intersect.

shamim · Answer

m1*m2=-1
its for two perpendicular line

shamim · Answer

we can try B option

shamim · Answer

can u tell the slope of ur first equation of line
m1=?

something doesn't look right

You don't exactly have to graph them. If you put them in slope-intercept form, you can look for slopes. They will be negative reciprocals.

I'm seeing  A. y = 2x – 7 x + 3y = 3 as one big equation that's not written correctly

usukidoll · Answer

meh I like graphing... I can see it and back up my claim :)
