Question

determine whether the lines are parallel perpendicular or neither
-10x-5y=2
8y=-4x+12

Answer 1

first try to get them into y=mx+b form
-10x-5y=2
+10x +10x
-5y=10x+2
divide by -5
y=-2x-(2/5)

8y=-4x+12
divide by 8
y=-(1/2)x+(3/2)
now look at the m-values -2 and -1/2 what do you think the answer is?

Answer 2

they are opposite and reciprocal so it is perpendicular right?

Answer 3

no they are not opposite they are both negative so it would be neither

Answer 4

oh ok thank you so much!!!! i appreciate it!!!

Answer 5

yep
