3y - 5x = 9<br> Y= -5/3x-12<br> Are the parallel
bija089 [108]

Answer:

Both lines are not parallel

Step-by-step explanation:

Given as :

Two lines equation are as :

3y - 5x = 9   And  y = - \frac{5}{3}x - 12

First line is now written in eq y = mx + c

Or,    3y = 5x + 9

Or,      y = \frac{5}{3}x +  \frac{9}{3}

So, Slop of this line ( m 1 ) =  \frac{5}{3}

     slop of second line ( m 2) is  \frac{- 5}{3}

∵ The slop of both lines are not equal , so the line are not parallel to each other .

Hence Both lines are not parallel     Answer
