Question

Choose the equation of the line passing through

the point (4, -2) and perpendicular to y = one thirdx - 7.

Answer 1

the slope formula for the line perpendicular to the line
y= 1/3 x -7
is m2=-1/m1
then what is the slope of the line perpendicular to it? is it m=1/3 or m=-3?
then use the point (4, -2)=(x1,y1), and the formula
y-y1=m(x-x1)
to find the equation of the line perpendicular to it
