Question

Write an equation perpendicular to 3x-y=10 through (-6, 1) in standard form.

Answer 1

3x-y=10
3x=10+y
3x-10=y
Your slope right now is 3, in order to find the perpendicular slope, you use the reciprocal. So 3 becomes (1/3)
In order to make sure your line passes through the poin, use the point slope formula
y-y1=m(x-x1)
y-1=(1/3)(x-(-6))
y-1=1/3x+2
y=1/3x+3

Answer 2

wait its y=-(1/3)x+3. forgot to add signs to the slope.

Answer 3

Thank you (:
