homework almost done?

anonymous · Answer

The slope of your line is  3/1

Do you know the slope of the perpendicular line?

hihi · Answer

Well im almost done, ive got 5 problems left, but il do them by myself, this question is hard for me though.

hihi · Answer

the slope of the perpendicular line is 1/3 right?

hihi · Answer

because isnt it supposed to be the opposite?

anonymous · Answer

-1/3

karatechopper · Answer

no the perpendicular is the opposite sign of the reciprocal

hihi · Answer

oh ya, forgot to add the negative, but i remembered it.

anonymous · Answer

Yes, the perpendicular slope is -1/3.  We will use the point-slope formula

y - y1 = m(x - x1)

we know the slope is -1/3 and we have  x = 3 and y = -4; therefore,

y + 4 = (-1/3)(x - 3)

Is this form oaky?
