Write the equation of the line in slope intercept form if the line goes through (-1,2) and is perpendicular to the line x-3y=-2

Answer 1

the given line is x+2 = 3y

(1/3)x + 2/3 = y

the given line has slope 1/3

the perpendicular line has slope -3

the perpendicular line has slope -3 and eats (-1,2)

B = y - mx = 2 - (-3)(-1) = 2 - 3 = -1

y = -3x - 1
