Question

What is the slope of the line that is perpendicular to the line whose equation is 3x + y = 4?
-3
-1/3
1/3
3

Answer 1

Rewrite it's equation in y=mx+c form

Now, for a line in the above form 'm' is its slope. And a line perpendicular to it will have the slope '-1/m'.

Answer 2

the second one ? -1/3

Answer 3

Umm no, slight mistake.

the line is rewritten as:
y = -3x + 4


Now what do you think?

Answer 4

3x + y = 4

y = -3x +4

Answer 5

\[-3(m)=-1\]

Answer 6

so the answer is 1/3

Answer 7

yay i got a medal lol

Answer 8

yes 1/3 right.
