Question

The slope of the line below is –. Write a point-slope equation of the line using the coordinates of the labeled point. A.y + 4 = (x + 4) B.y – 4 = –(x – 4) C.y – 4 = (x – 4) D.y + 4 = –(x + 4)

Answer 1

it is b because the formula is y-y1=m(x-x1)

Answer 2

Option B is correct answer.

Explanation:

Since given point is (4,4) and slope is 1 (as rise =run) but its going downward as x moves in positive direction

and slope point form of line is given by

y-y1= m(x-x1)

here m = -1 and point (x1,y1) = (4,4)

plugging these value is slope point form of line ,we get

y-4 = -1(x-4)

which gives option B as right answer.
