By brackets, I will assume you mean square brackets [].

Yes. The use of parentheses () is merely a matter of convention. It is possible, but not conventional, to use square brackets [] instead.

N equation of a line through (0, 2) which is perpendicular to the line y=3x+3y=3x+3 has slope

zhannawk [14.2K]

Something's not quite right here. What do you mean by "N?"

I could and will make assumptions regarding what you meant. (Feel free to correct me if need be.)

Find the equation of a line through (0,2) <span>which is perpendicular to the line y=3x+3. To find the slope of this perpendicular line, take the negative reciprocal of 3 (the slope of the given line). It is -1/3.

Using the point-slope form of the equation of a straight line:

y = (-1/3)x + 2 (answer)</span>
