Answer:
y = 3x + 2
Explanation:
use the negative reciprocal of the slope for a perpendicular line.
your given line has a slope of -1/3.
first, flip the fraction, and then flip the sign, and youre left with a slope of 3:
-1/3 become -3/1, which then becomes 3/1, which can be simplified to just 3.
i hope this helps.
as for 'b' in that equation, you substitute it for 2, which is the given y-intercept.
