Question

anonymous · Answer

i think its neither but i need confirmation

shubhamsrg · Answer

can you tell me slopes of both lines ?

anonymous · Answer

correct me if im wrong here but.....   2.5x and 2/9 x

anonymous · Answer

make the expression into the form of y= mx +c. where c is a constant and m is the slope of the line.  So for example 9x-2y=16.

9x-2y=16 
2y = 9x-16
y= 9/2 x - 8 

9/2 is the slope that line. Go ahead, Find the other.
