D:
\(2\)
Explanation:
No, this isn't the correct answer.
You probably forgot to put a negative sign in when rearranging the equation. Remember, when you have a "plus" on one side, moving it to the other side will make it a "minus".

Copy/paste the following tutorials:
- What is the gradient of a line if it is parallel or perpendicular to another?
Question analysis
Keep in mind that when two lines are parallel to each other, their gradients are the same. Now since we are given the equation of the first line, the gradient of the second line is just the gradient of the first line! To find the value of this gradient, convert the equation to gradient form, \(y=mx+c\). This is because the gradient can be easily seen when an equation is in gradient form (\(m\) is the gradient).
