Find the equation of the line that is perpendicular on the l
Find the equation of the line that is perpendicular on the line x - 3y = 1 and is passing through the point (-2, 3)
Solution
perpendicular to x - 3y = 1
finding slope of the line
3y = x - 1
y = x/3 - 1/3
slope = 1/3
slope of perpendicular line is negative reciprocal of this
hence slope of perpendicular line would be -3
passes throgh (-2,3)
point slope form of line is
y -y1 = m( x- x1)
plugging the values we get
y + 2 = -3 ( x-3)
y + 2 = -3x + 9
hence equation of line is
y = -3x + 7
