Question

HURRY Which is an equation in point-slope form for the line that passes through the points (−1,4) and (3,−4) ?

(A) y+4=2(x−3)

(B) y+4=−2(x−3)

(C) y−4=2(x+3)

(D) y−3=−2x+4)

Answer 1

y-4=-2(x+1)

Explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(-4-4)/(3-(-1))

m=-8/(3+1)

m=-8/4

m=-2

y-4=-2(x-(-1))

y-4=-2(x+1)
