The slope would be B) 0.05
(15a^4 - 30a^5 )/5a^2
= 5a^2(3a^2 - 6a^3) / 5a^2
= 3a^2 - 6a^3
or
= - 6a^3 + 3a^2
You are right on the question
A was A for the fun of it also I’m just putting anything down cause I put no question
2y+6x=0
-6x from both sides
2y=-6x+0
then divide by 2 to each side so it looks like this 2y/2=-6x+0/2
the 2 cancels 2y so you're left with y
Then divide -6/2=-3 and 0/2=0
y=-3x+0
Does that answer your question?
