Answer:
Step-by-step explanation:
okay I learned how to do this and here are some tips and tricks
when your trying to find if its parallel,perpendicular,or neither
it is best to find it in slope intercept form. so that way you can compare the two slopes
parallel=same slopes
perpendicular= if you change the sign and reciprocal
neither=it cant be flipped
the first equation is 3x-5y=10
goal:we have to convert this into slope intercept
1)find our x and y intercepts
10/3,0 and 0,2
2)write it in point slope form
y-2=3/5(x-10/3)
y-2=3/5x-2
y=3/5x
3/5 is our slope for the first equation
the second equation:10x+6y=-36
1)find x and y intercepts
0,-6
-18/5,0
now if you want to take a short cut here is what you do
-a/b
so.....
-10/6
=-5/3 is your slope for the 2nd equation
so 3/5 and -5/3
not parallel because it doesn't have the same slope different slopes!
its perpendicular because
if you flip the reciprocal and change the sign it would be 3/5
