Question

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

y+4=−2(x−3)

y−3=−2(x+4)

y+4=2(x−3)
y−4=2(x+3)

Answer 1

y+4=-2[x-3]

Explanation:

i took the test

Answer 2

(-1,4)(3,-4)
slope = (-4 - 4) / (3 - (-1) = -8/)3 + 1) = -8/4 = -2

y - y1 = m(x - x1)
slope(m) = -2
(3,-4)...x1 = 3 and y1 = -4
now we sub
y - (-4) = -2(x - 3) =
y + 4= -2(x - 3) <====
