Question

"Line A and Line B are parallel. The slope of Line A is -2. Find the value of x if the slope of Line B is 3x+3." Why doesn't that make sense?

Answer 1

Yea, my teacher gave me this question and it had me stumped for a while. Thanks!

Answer 2

Did the "why doesn't this make sense" come with the problem? If not, then I think there is a better answer to the question.

Answer 3

slope of Line B is 3x+3

(3x +3) = -2 because A and B are parallel.

Answer 4

I wrote that part. Good to know I wasn't wrong.

Answer 5

You were wrong, I think.

Answer 6

(3x +3) = -2 because A and B are parallel.

3x = -2 - 3
3x = -5
x = -5/3

So, x = -5/3 is the value of x that makes the blope of line B = -2 which means B and line A are parallel.

Answer 7

Oh. I get it. Sorta. Thanks for the help.

Answer 8

Answer 9

Don't worry, I think I got it now.
